A series of three-dimensional burls are formed in a filled-acrylic solid surface material by curing partially mixed steams of acrylic resin casting compositions with defined parameters of viscosity, density and surface tension.

Continuous method for formation of three dimensional burls in a solid surface material

A series of three-dimensional burls are formed in a filled acrylic solid surface material by curing two partially mixed casting compositions with defined parameters of viscosity, density and surface tension.

Formation of three dimensional burls in a filled acrylic solid surface material

A photographic, silver halide element that can be dried under rapid conditions during coating without deleterious effects on fog, kinks and other surface conditions, is described. This process can function with the addition of a small amount of a high boiling, aromatic alcohol to the emulsion prior to coating. Further improvements are noted with the addition of small amounts of a humectant and a plasticizer. The films resulting from this novel process can be handled without problems in the modern, automatic changing devices, for example.
