摘要:
A foamed, opacifying element has a thermal colorant image on either an opposing external surface and an internal surface of a porous substrate. The internal surface has a dry foamed composition disposed thereon as a dry opacifying layer that comprises: (a) 0.1-40 weight % of porous particles; (b) at least 10 weight % of an at least partially cured binder material; (c) at least 0.2 weight % of one or more additives comprising a surfactant; (d) less than 5 weight % of water; and (e) at least 0.002 weight % of an opacifying colorant different from all of the one or more (c) additives, which opacifying colorant absorbs predetermined electromagnetic radiation. The thermal colorant image is derived from thermal colorant transfer of sublimable colorants from a thermal donor element.

A light-blocking article is designed to be lightweight but effective to block most incident actinic radiation and can be designed into fabrics, curtains, and other materials. Such an article has an opacifying layer that is capable of blocking predetermined electromagnetic radiation. The article contains (a) porous particles comprising a continuous polymeric binder and pores within the continuous polymeric binder, the porous particles having a glass transition temperature of at least 25° C. and a mode particle size of at least 2 μm and up to and including 50 μm. The article also contains an opacifying colorant that absorbs the predetermined electromagnetic radiation (such as within 400 nm to 700 nm), in an amount of at least 0.001 weight % based on the total dry weight of the opacifying layer, and a matrix polymer in which the porous particles and opacifying colorant are dispersed.
