Abstract

Laminate precursor rolls are prepared by applying an aqueous foamed opacifying composition to a non-woven fabric, drying to form a dry foamed opacifying layer, applying an anti-blocking composition to the dry foamed opacifying layer. Each laminate precursor is rolled up for immediate or later use to make laminate decorative articles when the unrolled laminate precursor is laminated to the back side of a decorative fabric with or without an adhesive. The dry foamed opacifying layer is present at a dry coverage of less than or equal to 1000 g/m 2 . It is composed of (a) porous particles, (b′) a matrix material that is derived from a (b) binder material, (c) two or more additives comprising at least one foaming surfactant and at least one foam stabilizer, a very low amount of (d) an aqueous medium, and (e) an opacifying colorant that absorbs electromagnetic radiation having a wavelength of 380-800 nm.

(a) porous particles in an amount of at least 0.1 weight % and up to and including 35 weight %, each porous particle comprising a continuous polymeric phase and discrete pores dispersed within the continuous polymeric phase, the porous particles having a mode particle size of at least 2 μm and up to and including 50 μm and a porosity of at least 20 volume % and up to and including 70 volume %;
(b′) a matrix material that is derived from a (b) binder material having a glass transition temperature (T g ) of less than 25° C., which (b′) matrix material is present in an amount of at least 10 weight % and up to and including 80 weight %,
(c) two or more additives in an amount of at least 0.0001 weight % and up to and including 50 weight %, the two or more additives comprising at least one foaming surfactant and at least one foam stabilizer,
(d) an aqueous medium in an amount of less than 5 weight %, and
(e) an opacifying colorant in an amount of at least 0.002 weight % and up to and including 2 weight %, which opacifying colorant being a different material from the (a) porous particles, (b′) matrix material, and (c) two or more additives, and which opacifying colorant absorbs electromagnetic radiation having a wavelength of at least 380 nm and up to and including 800 nm,
all amounts of (a) porous particles, (b′) matrix material, (c) two or more additives, (d) aqueous medium, and (e) opacifying colorant being based on the total weight of the dry foamed opacifying layer.
