Abstract
Abstract A resin-coated metallic pigment which comprises metal particles coated with a resin produced from (i) an ethylenically double-bonded unsaturated carboxylic acid and/or (ii) a phosphoric mono or diester having an ethylenical double bond and (iii) a monomer having at least three ethylenical double bonds and exhibits an alkali resistance index of up to 1.0 when subjected to an appropriate test, and a process thereof.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
60 words
A resin-coated metallic pigment which comprises metal particles coated with a resin produced from (i) an ethylenically double-bonded unsaturated carboxylic acid and/or (ii) a phosphoric mono or diester having an ethylenical double bond and (iii) a monomer having at least three ethylenical double bonds and exhibits an alkali resistance index of up to 1.0 when subjected to an appropriate test.
Claim 2
Dependent Claim
60 words
A resin-coated metallic pigment which comprises metal particles coated with a resin produced from (i) an ethylenically double-bonded unsaturated carboxylic acid and/or (ii) a phosphoric mono or diester having an ethylenical double bond and (iii) a monomer having at least three ethylenical double bonds and exhibits an alkali resistance index of up to 1.0 when subjected to an appropriate test.
Claim 3
Dependent Claim
18 words
The resin-coated metallic pigment of claim 1, which undergoes no substantial agglomeration under definite heat stability test conditions.
Claim 4
Dependent Claim
17 words
The resin-coated metallic pigment of claim 1, wherein the phosphoric ester is 2-methacryloyloxyethyl phosphate or 2-acryloyloxyethyl phosphate.
Claim 5
Dependent Claim
63 words
A process for producing a resin-coated metallic pigment, which comprises the first step of dispersing a metallic pigment in an organic solvent and adding an ethylenically double-bonded unsaturated carboxylic acid and/or a phosphoric mono or diester having an ethylenical double bond and the second step of adding a monomer having at least three ethylenical double bonds and an initiator to polymerize said monomers.
Claim 6
Dependent Claim
63 words
A process for producing a resin-coated metallic pigment, which comprises the first step of dispersing a metallic pigment in an organic solvent and adding an ethylenically double-bonded unsaturated carboxylic acid and/or a phosphoric mono or diester having an ethylenical double bond and the second step of adding a monomer having at least three ethylenical double bonds and an initiator to polymerize said monomers.
Claim 7
Dependent Claim
28 words
The resin-coated metallic pigment of claim 2, wherein the monomer is a compound selected from the group consisting of trimethylolpropane triacrylate, trimethylolpropane trimethacrylate, tetramethylolmethane triacrylate, and tetramethylolmethane tetracrylate.
