Abstract
Abstract A curable resin composition comprising: (A) a compound having at least one curable acrylic radical, methacrylic radical or vinyl radial, or a mixture thereof; (B) an organic solvent containing an alcoholic organic solvent with an amount of not less than 40% by weight; (C) a compound having at least one pentavalent P with phosphoryl bonding; and (D) a polymerization initiator which when coated on the surface of molded inorganic or organic materials, the coating shows superiority in curing under atmosphere and the cured composition has excellent adhesion, surface hardness, resistance to scratch, resistance to abrasion, surface luster, transparency and antistatic property.

Claim 1
Independent Claim
99 words
A curable resin coating composition consisting essentially of: (A) at least one urethane meth(acrylate); (B) 5 to 1,500 parts by weight per 100 parts by weight component (A) of an organic solvent comprising an alcoholic organic solvent, said alcoholic organic solvent comprising at least 40% by weight of said organic solvent; (C) 0.005 to 25 parts by weight per 100 parts by weight component (A) of a compound having at least one pentavalent phosphor-containing phosphoryl group represented by the formula: ##STR11## (D) 0.01 to 20 parts by weight per 100 parts by weight component (A) of a polymerization initiator.
Claim 2
Dependent Claim
99 words
A curable resin coating composition consisting essentially of: (A) at least one urethane meth(acrylate); (B) 5 to 1,500 parts by weight per 100 parts by weight component (A) of an organic solvent comprising an alcoholic organic solvent, said alcoholic organic solvent comprising at least 40% by weight of said organic solvent; (C) 0.005 to 25 parts by weight per 100 parts by weight component (A) of a compound having at least one pentavalent phosphor-containing phosphoryl group represented by the formula: ##STR11## (D) 0.01 to 20 parts by weight per 100 parts by weight component (A) of a polymerization initiator.
Claim 3
Dependent Claim
34 words
The curable resin coating composition according to claim 1, wherein the amount of component (C) is in the range of from 0.0005 to 1.5 parts by weight per 100 parts by weight component (A).
Claim 4
Dependent Claim
117 words
The curable resin coating composition according to claim 1, wherein said phosphoryl group-containing compound (C) is represented by the formula: ##STR12## wherein R, R 1 and R 2 are selected from the group consisting of a hydrogen atom, an optionally branched, C 1 -C 24 alkyl group, an aryl group and an aralkyl group; provided that (i) at least one of R, R 1 and R 2 is not hydrogen; and (ii) when at least one of R, R 1 and R 2 is hydrogen, the phosphoryl group-containing compound may be in the form of a salt with a compound containing at least one member selected from the group consisting of primary, secondary, and tertiary amino groups.
Claim 5
Dependent Claim
35 words
