SOLUTION: This polyalkylene glycol monothiolactate of formula I [R is ethylene or propylene; (n) is an integer of 2-4], e.g. diethylene glycol monothiolactate. The compound of formula I is obtained by reacting 1mol equiv. thiolactic acid or alkyl thiolactate of formula II (R is H or a 1-4C alkyl) with preferably 1.5-3mol equiv. polyalkylene glycol of formula III at 80-180 deg.C. Water produced at this time is preferably removed. Furthermore, the compound of formula I as a reducing agent in a blended amount of 5-30% is mixed in an aqueous medium and the pH is preferably regulated to 6.5-8 to afford an excellent permanent waving composition.

摘要： PURPOSE:To provide the subject carrier capable of separating and recovering cultured cells from the surface of a base material without requirement of using a protease, a chemical reagent, etc., by coating the surface of the base material with a polymer containing cell-bonding groups and having a critical solution temperature to water within a prescribed range. CONSTITUTION:A polymer containing cell-bonding groups such as an ionic group (e.g. carboxylate group or sulfonate group) or an ion forming group (e.g. amidation group or esterification group) and having 0-80 deg.C critical solution temperature to water is prepared. As preferable examples of the polymer, an N-isopropylacrylamide/ sodium acrylate copolymer is exemplified. With the above-mentioned polymer, the surface of a base material is then coated utilizing a chemical reaction or a physical interaction, thus producing the objective carrier for cell culture. By culturing and growing cells using the resultant carrier, cultured cells cane readily be separated and recovered from the carrier.

摘要： PURPOSE:To form a latent image in high sensitivity to visible light and to be allowed to form a superior photopolymerized image by irradiation with the following ultraviolet rays by incorporating a dye-combined thioxathol derivative in the photosensitive composition. CONSTITUTION:The photosensitve composition contains a polymerizable compound, a photopolymerization initiator, and one of the thioxanthol derivatives represented by formula I in which each of Z1 and Z2 is a benzo- or naphtho-ring optionally substituted by a group except Dye; and Dye is a dye residue having a covalent bond to Z1 and/or Z2. The thioxanthols derivative are oxidized by the photopolymerization initiator to give the thioxanthones which serve as the polymerization initiator or sensitizer of hardening reaction by ultraviolet rays, thus permitting the latent image to be formed in high sensitivity to the visible light and to form the photopolymerized image by the following uniform irradiation with ultraviolet rays.
