Abstract

A thermoplastic resin composition includes a thermoplastic resin; a pearlescent pigment; and a pigment that is not the same as the pearlescent pigment, wherein the pearlescent pigment and pigment have da and db satisfying da<15 and db<15 in an L*a*b* colorimetric system, respectively.

First claim

What is claimed is:

1. A thermoplastic resin composition comprising:
a thermoplastic resin;
about 0.1 to about 1 part by weight of a pearlescent pigment based on about 100 parts by weight of thermoplastic resin; and
about 0.1 to about 1 part by weight of a pigment that is not the same as the pearlescent pigment based on about 100 parts by weight of thermoplastic resin,
wherein the pearlescent pigment consists of a synthetic mica and a coating consisting of TiO 2 and SnO 2 ,
wherein the pearlescent pigment and the pigment that is not the same as the pearlescent pigment are in the same color family, and
wherein the thermoplastic resin is an acrylonitrile-butadiene-styrene (ABS)/polymethylmethacrylate (PMMA) blend resin.

2. The thermoplastic resin composition of claim 1 , wherein the pigment that is not the same as the pearlescent pigment is an organic pigment, an inorganic pigment, or a combination thereof.

3. The thermoplastic resin composition of claim 1 , wherein the pearlescent pigment has an average particle diameter of about 0.1 to about 50 μm.

4. The thermoplastic resin composition of claim 1 , wherein the thermoplastic resin composition further comprises an inorganic particle comprising a glass particle, mica, graphite, a pearl particle, or a combination thereof.

5. The thermoplastic resin composition of claim 4 , including the inorganic particle in an amount of about 0.1 to about 3 parts by weight based on about 100 parts by weight of the thermoplastic resin.
