Abstract: An article and its method of manufacture. The article comprises a base provided with a surface having a surface pattern. The surface pattern has at least one edge or boundary defined by at least one continuous retaining means. At least a portion of the retaining means is a contiguous low energy surface. The article additionally optionally comprises a volume or hardened resin covering only the surface pattern.The method of the invention comprises forming the continuous retaining means comprising a contiguous low energy surface to define the boundary of the pattern area, introducing a liquid resin into the pattern area and hardening the resin to form an elevated boss.

Abstract: An article comprising a thermoplastic polymer having an essentially planar surface provided with a surface pattern defined and encompassed by at least one continuous self-connecting retaining dam; at least a portion of the dam comprising at least one debossed region between at least two essentially parallel raised ridges; a further article comprising the foregoing article having a boss formed from a hardened resin over the surface pattern to a depth at least equal to the height of the highest of the raised ridges; and a method for manufacturing the articles by heating the surface to a temperature above the deformation temperature of the polymer and impressing the surface with a debossing die to form the portion of the article having the debossed region and raised ridges and introducing a liquid resin into the surface pattern followed by solidifying the resin to form the article having the boss.

Abstract: A composition for increasing flame resistance of a step-reaction polymer comprising a metal salt of certain organic acids in combination with certain organic acids or their ammonium salts, the method of treating the step-reaction polymer with the composition and the resulting treated polymer.

Abstract: A flame resistant organic polymer which decomposes into fragments containing acidic and/or basic groups and the process for making same comprising treating an organic polymer which decomposes into said fragments with from about 0.5 to about 25 weight percent of a compound which contains at least one functional radical selected from --0--, --S-- and --N-- and at least one carboxyl or mercapto group which is able to dissociate in water to provide a free positively charged ion.
