摘要： PURPOSE:To enable favorable printing to be performed by various printing methods without need for a pretreatment, by using a specified chlorinated polyethylene. CONSTITUTION:A chlorinated polyethylene to be used for a plastic-made printing material is preferably a chlorinated polyethylene having a chlorine content of 10-50wt.% which is obtained by chlorinating a polyethylene having a molecular weight of 10000-200000 by a solution method or an aqueous suspension method. The printing material is used in any of various forms such as a film or sheet prepared from the chlorinated polyethylene alone or a mixture of the chlorinated polyethylene with a polymer compatible therewith, optionally with addition of additives, a composite laminate of the film or sheet with a composite base material, and a material obtained by coating the film or sheet or the composite base material. The printing material thus obtained is excellent for use as a printing material for gravure, offset printing, letterpress printing, hot stamping, electrostatic printing or the like.

摘要： PURPOSE:To obtain the title composition excellent in oil and heat resistances by mixing a mixture of chlorinated PE and/or chlorosulfonated PE with an epichloro-hydrin rubber in a specified ratio with powdery ferrite in a specified mixing ratio. CONSTITUTION:100 pts.wt. mixture of 30-90wt.% chlorinated PE and/or chlorosulfonated PE with 70-10wt.% epichlorohydrin rubber (e.g. epichlorohydrin homopolymer) is mixed with 300-1300 pts.wt. powdery ferrite.

摘要： PURPOSE:To enable assembly and disassembly work of blocks by fitting only an inward coupling wall provided to the end of one block into an outward coupling groove formed on the end of the other block from above to constitute so as to easily couple the blocks. CONSTITUTION:A pool is constituted of a pool body 10 forming an endless pool side wall and a bag shaped waterproof sheet 11 fixed to the body 10 so as to cover the internal wall surface of the body 10 and the bottom between them. After that, the body 10 includes respectively a hollow and about a trapezoidal side of four circular blocks 12, four linear blocks 13 and four linear blocks 14 to form. Then, coupling members 19 are respectively fixed to the inside of a coupling wall consisting of the ends of the side wall blocks 12 and the end of the side wall blocks 14. According to the constitution, the blocks can be coupled by fitting only an inward coupling wall of one block into an outward coupling groove of the other block from above, and the disassembly work can be done by only removing the inward coupling wall from the other outward coupling groove by lifting one block.

摘要： PURPOSE:To prepare a plastic printing material which is excellent in the processability, flexibility without addition of a plasticizer, and printability without surface pretreatment by using a specific chlorinated ethylene polymer and/or chlorosulfonated ethylene polymer as the raw material. CONSTITUTION:A plastic printing material is prepd. by using, as the raw material, a polymer or polymer mixture selected from the group consisting of: a chlorinated ethylene polymer contg. 10 to 70wt.% chlorine, obtd. by chlorinating an ethylene polymer having an MW of 3000 to 1000000 (excluding a chlorinated polyethylene contg. 10 to 50wt.% chlorine, obtd. by chlorinating a polyethylene having an MW of 10000 to 200000); a chlorosulfonated ethylene polymer contg. 0.1 to 3wt.% sulfur and 10 to 70wt.% chlorine, obtd. by chlorosulfonating said ethylene polymer having an MW of 3000 to 1000000: and a mixture of at least two polymers selected from the group consisting of said chlorinated ethylene polymer, said chlorosulfonated ethylene polymer, and other polymers. The resulting material is excellent in the processability, plasticity without addition of a plasticizer, and printability without surface pretreatment, and can be printed in various ways.

摘要： PURPOSE:To enable assembly and disassembly work by making it possible to couple easily side wall blocks forming a pool body with each other to constitute. CONSTITUTION:A pool is constituted of a pool body 10 forming an endless pool side wall and a bag shaped waterproof sheet 11 fixed to the body 10 so as to cover the internal wall surface of the body 10 and the bottom between them. After that, the body 10 includes respectively a hollow and about a trapezoidal four circular blocks 12 with an opening of the lower end, four linear blocks 13 and four linear blocks 14 to form. Coupling members 19 are respectively fixed to the inside of a coupling wall 17 consisting of the ends of the side wall blocks 12 and the end of the side wall blocks 14. Accordingly, connection and disconnection of the side wall blocks each other can be easily made, and a storage space can be reduced if disassembly side blocks are piled up for storage.

摘要： PURPOSE:To provide wear resistance, flection resistance, and resistance to wrinkles, and to obtain a rigid fixation surface which has good surface glossiness and superior contamination resistance by carrying out a heat treatment at 160-250 deg.C for 5-30sec after forming an image on the surface of a body to be printed when a copy is taken by using toner. CONSTITUTION:For example, a normal constant-temperature heater, a heat roll, or infrared-ray heater with a reflecting plate is provided as a fixation processing means and copied printed matter is passed through a heating atmosphere. This method is applicable similarly to a polyethylene chloride sheet, sheet containing polyethylene chloride, or specified copying form and a sufficiently stable print image is obtained. Then the fixation processing temperature is 160-250 deg.C and the time is short or 5-30sec. In general, the time is preferably 5-20sec almost is 180 deg.C. Consequently, there is not the possibility of the contamination of a print part due to the sticking of other printed matter, not to mention the bleeding and desorption of a copy image, and the stable printed matter which can be stored permanently is obtained.
