Abstract
Abstract A colored resin composition characterized in that it has a matrix of a thermoplastic polymer (A), typically a polyester, and a thermoplastic polymer (B), typically a styrene polymer, which is dispersed in the matrix and is separated in phase from the matrix, and the polymer (B) is filled with substantially the entire quantity of a colorant. Since the colorant is blended in only the dispersed phase polymer (B), deterioration due to the colorant of various characteristics, such as bleed-out of the colorant, is prevented in the colored resin composition according to this invention.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
98 words
A colored resin composition comprising: a matrix phase comprised of a thermoplastic polyester and a thermoplastic modified polyester graft-copolymerized with styrene; a dispersed phase comprised of a thermoplastic styrene polymer, the dispersed phase being dispersed in the matrix phase and being separated in phase from the matrix phase; and a colorant having greater affinity for the thermoplastic styrene polymer of the dispersed phase than for at least one of the thermoplastic polyester and the thermoplastic modified polyester graft-copolymerized with styrene of the matrix phase so that substantially the entire amount of the colorant remains in the dispersed phase.
Claim 2
Dependent Claim
98 words
A colored resin composition comprising: a matrix phase comprised of a thermoplastic polyester and a thermoplastic modified polyester graft-copolymerized with styrene; a dispersed phase comprised of a thermoplastic styrene polymer, the dispersed phase being dispersed in the matrix phase and being separated in phase from the matrix phase; and a colorant having greater affinity for the thermoplastic styrene polymer of the dispersed phase than for at least one of the thermoplastic polyester and the thermoplastic modified polyester graft-copolymerized with styrene of the matrix phase so that substantially the entire amount of the colorant remains in the dispersed phase.
