Patent ID: 7595353

Claim:
A photocurable polymer composition comprising: (i) a fluorine-containing polymer (A); and (ii) a fluorine-free polymer (B), wherein the fluorine-containing polymer (A) is a copolymer produced from (I) at least one radically-polymerizable fluorine-containing monomer (a1) represented by a general formula X—Y, in which X is a radically-polymerizable functional group selected from the group consisting of CH 2 ═C(CH 3 )—COO— and CH 2 ═CH—COO—; and Y is a fluorine-containing functional group; and (II) another radically-polymerizable monomer (a2) having at least one crosslinkable functional group elected from the group consisting of epoxy and oxetanyl, wherein the fluorine-containing functional group Y is represented by the following Formula (I): wherein in the Formula (I): each of R f 1 to R f 7 are independently are at least one of (i) a linear or branched fluoroalkyl which has approximately 1 to approximately 20 carbon atoms and in which arbitrary methylene may be replaced by oxygen, (ii) a fluoroaryl which has approximately 6 to approximately 20 carbon atoms and in which one or more hydrogen is replaced by fluorine or —CF 3 , (iii) a fluoroarylalkyl which has approximately 7 to approximately 20 carbon atoms and in which one or more hydrogen in the aryl is replaced by fluorine or —CF 3 , (iv) a linear or branched alkyl which has approximately 1 to approximately 20 carbon atoms and does not contain fluorine, and in which arbitrary methylene may be replaced by oxygen, (v) an aryl which has approximately 6 to approximately 20 carbon atoms and does not contain fluorine, and (vi) an arylalkyl which has approximately 7 to approximately 20 carbon atoms and does not contain fluorine; wherein at least one of R f 1 to R f 7 is fluoroalkyl, fluoroaryl, or fluoroarylalkyl; and wherein R 2 is a single bond or alkylene which has approximately 1 to approximately 20 carbon atoms and in which arbitrary methylene may be replaced by oxygen and wherein the fluorine-free polymer (B) is a copolymer produced from a radically-polymerizable carboxyl-containing monomer (b1) and another radically-polymerizable monomer (b2), and wherein the radically-polymerizable carboxyl-containing monomer (b1) is methacrylic acid; and the radically-polymerizable monomer (b2) contains at least one of benzyl (meth)acrylate, N-phenylmaleimide, 2-hydroxyethyl (meth)acrylate, styrene, glycidyl (meth)acrylate, 3-ethyl-3-oxetanylmethyl (meth)acrylate, cyclohexyl (meth)acrylate, and a radically-polymerizable monomer represented by the following Formula (II): wherein Formula (II), R 1 is at least one of hydrogen and methyl, R 2 is at least one of hydrogen and alkyl having approximately 1 to approximately 5 carbon atoms, and n is an integer of approximately 1 to approximately 5.
