Patent ID: 7816419

Claim:
A photocurable and thermosetting coating composition which is solventless and liquid at room temperature comprising: a silicone resin represented by a siloxane unit of the following formula (1): (R 1 R 2 R 3 SiO 1/2 ) a (R 4 R 5 SiO 2/2 ) b (R 6 SiO 3/2 ) c (SiO 4/2 ) d (O 1/2 X) e (1) wherein X is hydrogen atom or an alkyl group containing 1 to 4 carbon atoms; R 1 to R 6 are respectively at least one monovalent organic group which is a monovalent aliphatic hydrocarbon group containing 1 to 6 carbon atoms or a monovalent aromatic hydrocarbon group containing 6 to 10 carbon atoms optionally substituted with a substituent selected from phenyl group, fluorine atom, chlorine atom, bromine atom, (meth)acryloxy group, epoxy structure-containing group, mercapto group, isocyanate group, amino functional group, perfluoroalkyl group, and poly(hexafluoropropylene oxide) structure-containing group; with the proviso that at least one of the R 1 to R 6 is a group represented by the following formula (2): CH 2 ═C(R 7 )COOCH 2 — (2) wherein R 7 is hydrogen atom or methyl group; and that the amount of the siloxane unit substituted by the organic group represented by the formula (2) is 20 to 100% by mole of all siloxane units; a is on average 0≦a<0.4; b is on average 0≦b<0.5; c is on average 0<c≦1; d is on average 0≦d<0.4; e is on average 0≦e<0.2; and a+b+c+d=1, wherein the silicone resin contains a siloxane unit substituted by a group containing poly(hexafluoropropylene oxide) structure at an amount of 0.1 to 20% by mole of all siloxane units and a siloxane unit substituted by methyl group at an amount of 1 to 10% by mole of all siloxane units.
