摘要： A microbicidal organic polymer material for use in manufacturing of contact lenses, catheters, condoms, surgical sutures and gloves, medical examination devices and similar uses is provided by polymers to which is tightly adsorbed a disinfectant organic dye. Many polymers such as polyvinyl chloride and acrylic polymers show exceptional avidity for a number of microbicides, of acidic, basic, aromatic and/or hydrophobic character such as methylene blue and gentian violet. Consequently, devices constructed of these polymeric materials release no free dye to an aqueous solution. The material is generally a natural or synthetic polymer that releases no particles or fines into wounds or body orifices. Presence of adsorbed disinfectant organic dye allows the polymer to inhibit microbial growth in a number of different situations. Several common microbes are killed by being incubated in the present of an embodiment of the invention that contains a combination of methylene blue and gentian violet. Absorption of meglumine to the polymers in combination with the organic dyes enhances the anti-infective properties of the material.

摘要： Polymeric monoliths having high stiffness and strength can be produced by heating an assembly of polymer fibres under a contact pressure to a temperature at which a proportion of the fibre is selectively melted and then compressing the assembly. Preferably at least 5% of the polymer is melted so that on compression the molten materials fills the voids within the assembly. The use of polyolefin fibres especially melt spun polyethylene fibres is preferred. The products are useful e.g. as orthodontic brackets, bone prostheses and in body armour.

摘要： The present invention relates to a thermal transfer ink layer composition, wherein polyvinylacetal resin and cellulose derivatives are used in a mixture for the binder in the thermal transfer ink layer composition of the sublimation thermal transfer ink ribbon, or the another type of a binder is mixed into the mixture of polyvinylacetal resin and cellulose derivatives and so used therein. As a result, the adhesion between the thermal transfer ink layer and substrate film, and the gradation property of printed images are improved as compared to the case in which the respective binders are used individually. More particularly, the present invention relates to the thermal transfer ink layer composition of the sublimation thermal transfer ink ribbon, which can yield high quality images by means of the aforementioned improvements.
