Claim 0:
1. A molded-in-color composition comprising:
a) 50 to 80 wt. %, based on the total weight of the molded-in-color composition, of a polyolefin resin composition;
b) 5 to 25 wt. %, based on the total weight of the molded-in-color composition, of at least one elastomer;
c) greater than 0 to 2 wt. %, based on the total weight of the molded-in-color composition, of an additive package;
d) greater than 0 to 2 wt. %, based on the total weight of the molded-in-color composition, of one or more colorants; and
e) less than 4 wt. %, based on the total weight of the molded-in-color composition, of a mineral filler, wherein the mineral filler comprises talc,
wherein the molded-in-color composition has a ΔE* value≤2.0 (compared to a painted color master), a gloss measured at 60° from about 76 to about 90 GU, density from about 0.89 to about 0.97 g/cm3, a melt mass flow rate (MFR) from about 15 to about 40 g/10 min (ASTM D 1238, 230° C./2.16 kg), a flexural modulus between about 600 to about 2000 MPa, an ash content from 0.001 to 8.0 wt. %, based on the total weight of the molded-in-color composition, and an as-molded shrinkage between about 0.6% and about 1.4%.
