Abstract
Abstract A non-fogging coating composition, which comprises (A) 0 to 50 parts by weight of epoxy group-containing organic silane compounds or partial hydrolyzates thereof, (B) 20 to 80 parts by weight of a polyhydric alcohol having an ethylene oxide chain, (C) 10 to 75 parts by weight of a polymer or copolymer having at least 20% by weight of repeating structural units having the general formula <IMAGE> wherein, R4 and R5 independently stand for H or a lower alkyl group or carbonyl group and X stands for a side chain possessing an epoxy group, and (D) a catalytic amount of a curing catalyst. And a shaped article of polycarbonate type resin coated therewith.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
281 words
A non-fogging transparent coating composition free of organophosphate ester and amine-aldehyde resin crosslinking agents and complex salt photoinitiators, which comprises: (A) an effective amount up to 50 parts by weight ##STR27## of at least one compound selected from the group consisting of epoxy group-containing organic silane compounds represented by the general formula (1): ##STR28## wherein R 1 stands for an organic group having an epoxy group, R 2 for a hydrogen atom, a hydrocarbon group having 1 to 6 carbon atoms or a vinyl group, R 3 for a hydrocarbon group having 1 to 5 carbon atoms, an alkoxyalkyl group or an acyl group having 1 to 4 carbon atoms, a for an integer having the value of 1 to 3 and b 0 or for an integer having the value of 1 to 2, providing that a+b≦3 is satisfied, and partial hydrolyzates thereof, (B) 20 to 80 parts by weight selected from triethylene glycol and a polyhydric alcohol which has an ethylene oxide chain and a molecular weight of 200 to 2000 and is capable of reacting with a mixture of the components (A) and (C) to form a coating film, (C) 10 to 75 parts by weight of a polymer or copolymer containing at least 20% by weight of repeating structural units represented by the general formula (2): ##STR29## wherein, R 4 and R 5 independently stand for a hydrogen atom, a lower alkyl group or a carboxyl group and X stands for a side chain possessing an epoxy group, and (D) a catalytic amount of a curing catalyst, providing that the total of the amounts of the aforementioned components (A), (B) and (C) is 100 parts by weight.
Claim 2
Dependent Claim
281 words
A non-fogging transparent coating composition free of organophosphate ester and amine-aldehyde resin crosslinking agents and complex salt photoinitiators, which comprises: (A) an effective amount up to 50 parts by weight ##STR27## of at least one compound selected from the group consisting of epoxy group-containing organic silane compounds represented by the general formula (1): ##STR28## wherein R 1 stands for an organic group having an epoxy group, R 2 for a hydrogen atom, a hydrocarbon group having 1 to 6 carbon atoms or a vinyl group, R 3 for a hydrocarbon group having 1 to 5 carbon atoms, an alkoxyalkyl group or an acyl group having 1 to 4 carbon atoms, a for an integer having the value of 1 to 3 and b 0 or for an integer having the value of 1 to 2, providing that a+b≦3 is satisfied, and partial hydrolyzates thereof, (B) 20 to 80 parts by weight selected from triethylene glycol and a polyhydric alcohol which has an ethylene oxide chain and a molecular weight of 200 to 2000 and is capable of reacting with a mixture of the components (A) and (C) to form a coating film, (C) 10 to 75 parts by weight of a polymer or copolymer containing at least 20% by weight of repeating structural units represented by the general formula (2): ##STR29## wherein, R 4 and R 5 independently stand for a hydrogen atom, a lower alkyl group or a carboxyl group and X stands for a side chain possessing an epoxy group, and (D) a catalytic amount of a curing catalyst, providing that the total of the amounts of the aforementioned components (A), (B) and (C) is 100 parts by weight.
Claim 3
Dependent Claim
