Paint coated article

Claim 2

A paint-coated article having excellent distinctness of image, flop and covering power which comprises: a substrate, coated on the substrate an outer paint layer and an inner paint layer, each of said layers comprising a polymeric binder and reflective flakes dispersed therein, the flakes of said outer layer being of relatively large average size and present in a concentration such that the layer is light transmissive, the flakes of said inner layer being of relatively smaller average size, and the coverage of said inner layer being sufficient that the total paint coating is opaque and wherein the flake concentration in the outer layer is from about 0.3 to 5.0 weight percent, and wherein the average dimension across a major flake axis of flake in the outer layer is from about 10 to 100 μm, and the average dimension across a major flake axis of flake in the inner layer is from about 1 to 20 μm, with the proviso that the average dimension across a major flake axis of flake in the outer layer is at least three times that of flake in the inner layer.

Claim 3

The article of claim 1 wherein the reflective flakes are metal flakes.

Claim 4

The article of claim 2 wherein the coverage of the metal flakes in the inner layer is from about 0.01 to 10 mg/sq. cm.

Claim 5

The article of claim 2 wherein the dry thickness of the outer layer ranges from about 0.03 to 0.07 mm and the dry thickness of the inner layer ranges from about 0.01 to 0.03 mm.

Claim 6

The article of claim 2 wherein the combined thickness of the paint layers ranges from about 0.04 to 0.10 mm.

Claim 7

The article of claim 2 wherein the distinctness of image is at least 80 when measured in accordance with ASTM TEST E-430.

Claim 8

The article of claim 2 wherein the 20 degree gloss is at least 80 when measured in accordance with ASTM TEST D-2457.

Claim 9

A flexible and stretchable sheet material adapted for use in a thermoforming process in which it is stretched and bonded to a three-dimensional substrate to form thereon a decorative coating exhibiting a high degree of geometric metamerism, said sheet material comprising: (1) a thin, essentially planar, stretchable thermoplastic polymeric carrier film of uniform thickness; said carrier film having heat-softening and tensile elongation properties which adapt it to use in said thermoforming process; and (2) a thin coating of paint of substantially uniform thickness on one surface of said thermoplastic polymeric support, said paint coating comprising an outer layer and an inner layer, each of said layers comprising a polymeric binder and reflective flakes dispersed therein, the flakes of said outer layer being of relatively large average size and present in a concentration such that the layer is light transmissive, the flakes of said inner layer being of relatively smaller particle size, and the coverage of said inner layer being sufficient that the total paint coating is opaque and wherein the flake concentration in the outer layer is from about 0.3 to 5.0 weight percent, and wherein the average dimension across a major flake axis of flake in the outer layer is from about 10 to 100 μm, and the average dimension across a major flake axis of flake in the inner layer is from about 1 to 20 μm, with the proviso that the average dimension across a major flake axis of flake in the outer layer is at least three times that of flake in the inner layer.

Claim 10

A flexible and stretchable sheet material adapted for use in a thermoforming process in which it is stretched and bonded to a three-dimensional substrate to form thereon a decorative coating exhibiting a high degree of geometric metamerism, said sheet material comprising: (1) a thin, essentially planar, stretchable thermoplastic polymeric carrier film of uniform thickness; said carrier film having heat-softening and tensile elongation properties which adapt it to use in said thermoforming process; and (2) a thin coating of paint of substantially uniform thickness on one surface of said thermoplastic polymeric support, said paint coating comprising an outer layer and an inner layer, each of said layers comprising a polymeric binder and reflective flakes dispersed therein, the flakes of said outer layer being of relatively large average size and present in a concentration such that the layer is light transmissive, the flakes of said inner layer being of relatively smaller particle size, and the coverage of said inner layer being sufficient that the total paint coating is opaque and wherein the flake concentration in the outer layer is from about 0.3 to 5.0 weight percent, and wherein the average dimension across a major flake axis of flake in the outer layer is from about 10 to 100 μm, and the average dimension across a major flake axis of flake in the inner layer is from about 1 to 20 μm, with the proviso that the average dimension across a major flake axis of flake in the outer layer is at least three times that of flake in the inner layer.
