Abstract: A composite panel is provided which includes a resin matrix having embedded therewithin alternating layers of particulates and flexible sheeting. The composite panel is capable of supporting its own weight and exhibits impact resistance and shatter resistance. Preferably, the resin is transparent, the particulates are decorative, and the flexible sheeting becomes transparent upon curing of the resin. The composite panels are included within articles such as tables, desks, other furniture, vertical partitions, decorative panels, doors, windows and floors. Also included is a method of making the composite panels by molding layers of these materials within an open mold.

Abstract: In the production of a backed nonwoven fabric by needle-punching, calendaring or heat treatment of a spun-bonded or fiber nonwoven produced from a polymer or synthetic fiber, subsequent further processing of the resultant nonwoven with an aqueous solution or dispersion of a crosslinkable polymer or melamine resin and subsequent drying and coating with bitumen or PVC plastisol, the improvement wherein the solution or dispersion contains silica sol in a quantity such that the weight ratio of polymer:SiO.sub.2 is from about 3:1 to 1:3 and the weight ratio of melamine resin:SiO.sub.2 is from about 10:1 to 1:1. The products have improved tear strength and dimensional stability.

Abstract: A retroreflective composition of the present invention comprises non-volatile matrix material, volatile constituent, and a plurality of retroreflective microsphere beads wherein the ratio of the volume of matrix material to the volume of retroreflective microsphere beads is in the range of 75% to 185%, and is optimally suitable for use on fabrics.
