摘要： Foamable aqueous compositions can be foamed and applied to porous substrates to make light-blocking dry opacifying elements. Such compositions have 0.05-15 weight % of porous particles; at least 20 weight % of a binder; at least 0.0001 weight % of additives (including a surfactant); water; and at least 0.001 weight % of an opacifying colorant. Each porous particle includes a continuous polymeric phase and discrete pores; a mode particle size of 2-50 μm; and a porosity of 20-70 volume %. The continuous polymeric phase Tg is >80° C. and has a polymer viscosity of 80-500 centipoises at an ethyl acetate shear rate of 100 sec−1 at a concentration of 20 weight % at 25° C. The dry opacifying element light blocking value is at least 4 and has a luminous reflectance>40% as measured by the Y tristimulus value. The foamed aqueous composition has a foam density of 0.1-0.5 g/cm3.

摘要： An aqueous non-foamed functional composition formulation is disposed on a foamed opacifying layer in light-blocking, foamed opacifying elements. This non-foamed functional composition formulation has 0.5-15% solids and essential (i) and (iv) components and optional (ii), (v), (vi), and (vii) components. The components (i) untreated synthetic silica (fumed silica or precipitated silica) at 0.5-10 weight %; and a (iv) water-soluble or water-dispersible organic polymeric binder having a glass transition temperature (Tg) below 25° C. The weight ratio of the (i) untreated synthetic silica to the (iv) water-soluble or water-dispersible organic polymeric binder is 10:1 to 1:1. The optional components include: a (ii) solid or non-solid lubricant; a (v) crosslinking agent; a (vi) thickener; and a (vii) coating aid. Glass particles can also be present. The presence of the (i) untreated synthetic silica provides improved brightness, e.g. an L* value of at least 80, and uniform coatings in the resulting, foamed opacifying element.

摘要： A non-foamed aqueous composition can be applied to fabric substrates to provide non-foamed light-attenuating coatings in resulting coated fabric substrates that produce reduced glare from incident outside light. The non-foamed aqueous composition used to make these coated fabric substrates has a 5-50% solids and a zero shear viscosity of 100-1000 mPa-sec at 25° C. This composition has components i) through iv): i) porous particles at 0.1-20 weight %, and optionally an opacifying colorant; ii) a film-forming binder material comprising at least a chlorinated polymer at 4-20 weight %; iii) a white inorganic particulate filler material having a refraction index (RI) greater than 2 and a median particle size of less than 1 μm, at 5-16 weight %; and iv) a white low-density particulate hydrated alumina having a median particle size of less than or equal to 3 μm, at 2-16 weight %.

摘要： An aqueous functional composition formulation is used to provide a top layer or pattern in light-blocking opacifying elements. This functional composition formulation has 0.5-15% solids and the essential (i) and (iv) components and any optional (ii), (v), (vi), and (vii) components. The essential components are (i) fumed silica particles at 0.5-10 weight %; and a (iv) water-soluble or water-dispersible organic polymeric binder having a glass transition temperature (Tg) below 25° C. The weight ratio of the (i) fumed silica particles to the (iv) water-soluble or water-dispersible organic polymeric binder is 10:1 to 1:5. The optional components include: a (ii) solid or non-solid lubricant; a (v) crosslinking agent; a (vi) thickener; and a (vii) coating aid. Glass particles can also be present. The presence of the (i) fumed silica provides improved brightness, e.g. an L* value of at least 80, and uniform coatings in the opacifying element.
