PURPOSE: An antistaining agent, consisting of a polymer having a specific structure and a hydrophilic resin and having durable water absorbing, oil repellent and antistaining function. n CONSTITUTION: A antistaining agent consisting of (A) 5W95pts.wt. polymer having 10W100pts.wt. structural units expressed by the formula [R f is 3W21C fluoroalkyl; R 1 is H or 2W4C acyl; R 2 WR 5 are H or 1W2C alkyl; A is -CH 2 CH (OR 1 )CH 2 -OCO-, -CO-, -(CH 2 ) k N(R 2 )CO- (k is an integer 1W10) or -(CH 2 ) k -; h is an integer 0W5; p is an integer 1W40; q and r are integers 0W40] and (B) 95W5pts.wt. hydrophilic resin. When 1%n50pts.wt. water and oil repellent is further added to 1W95pts.wt. polymer (A) and 5W95pts.wt. resin (B), a water and oil repellent antistaining agent is obtained. n COPYRIGHT: (C)1987,JPO&Japio |
