COATING MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a coating material which contains a vinylic polymer containing carbosiloxane dendrimer structures on side chains as a main agent and has excellent weather resistance, especially excellent gloss retainability and excellent water repellence persistency. SOLUTION: This coating material contains a vinylic polymer containing carbosiloxane dendrimer structures on side chains as a main agent. The carbosiloxane dendrimer structures are expressed by formula I Z is a divalent organic group; (p) is 0 or 1; R1 is a 1-10C alkyl or an aryl; and Xi is a silylalkyl of formula II [R2 is a 2-10C alkylene; R3 is a 1-10C alkyl; Xi+1 is H, a 1-10C alkyl or the like; (i) is 1-10; and (ai) is 0-3]}. The vinylic polymer is preferably obtained by copolymerizing (A) 0-99.9 pts.wt. of a vinylic monomer with (B) 100-0.1 pts.wt. of a carosiloxane dendrimer containing a radically polymerizable organic group of formula III (Y is an organic group).
