  • Patent number: 9950559
    Abstract: This disclosure is directed to a multilayered laminate, comprising (a) a support substrate having at least one releasable major surface; (b) a transparent overcoat formed of a first coating composition on the releasable major surface of the support substrate, wherein the first coating composition comprises an aqueous polymer dispersion having a particle size in the range of 30 to 400 nm; (c) a stone-like topcoat system on the transparent overcoat, wherein the stone-like topcoat system comprises a multicolored spot layer and a background color layer; (d) an adhesive primer coat formed of a second coating composition on the stone-like topcoat system, wherein the second coating composition comprises an aqueous polymer dispersion selected from aqueous acrylic dispersions, aqueous organic silicone dispersions and aqueous vinyl acetate dispersions, wherein the transparent overcoat in the multilayered laminate, when released from the support substrate, a gloss of at least 60% at 60°.
