PURPOSE:To improve the sticking property between the titled composition and a substrate by using a specified acrylic type linear copolymer for the titled composition. CONSTITUTION:The titled composition contains the linear copolymer contg. 0.1-50wt.% an acrylate shown by formula I, an ethylenically unsatd. compd. capable of polymerizing with a photopolymerization initiator such as the (meth) acrylate and the photopolymerization initiator such as a benzophenone, as main components. In the formula, X is H atom. or methyl group, Y is 1-5C alkylene group, Z is 0-10C alkylene or phenylene group, etc. The concrete example of formula I is exemplified by a compd. shown by formula II, etc. And, the (meth)acrylate etc. is used for the comonomer of said copolymer. Thus, the composition having the excellent sticking property to a jagged substrate is obtd. |
