Abstract: 1499447 Materials comprising a polyurethane cellular layer RHONE-POULENC INDUSTRIES 13 Nov 1975 [18 Dec 1974] 46911/75 Heading C3R [Also in Division B2] A process for the preparation of a material comprising a polyurethane cellular layer comprises (a) coating the material with a polyurethane-based expandable composition comprising a polyurethane prepolymer possessing terminal NCO groups and a catalyst for the formation of carbodiimide groups, the prepolymer having been prepared by the reaction of a polyisocyanate with a polyol having an average molecular weight per OH group of 200 to 6000, the polyol having an average number  of functional groups of at most equal to 3, the said catalyst being present in an amount from 0À1 to 15% wt. of the prepolymer, and (b) heat treating the coated material at 100‹ to 180‹ C. to cause expansion and cross-linking of the polymer. The catalyst is preferably a phospholine or phospholidine or a sulphide or oxide thereof or a 2,4,6-tri-(dialkanolamine)-triazine. Suitable polyols include diethylene glycol, dipropylene glycol; polyhydroxylic polyethers or polyesters; α,# - dihydroxy - polyesteramides, polyurethanes and hydrocarbons; optionally modified castor oil, and etherified silanols or siloxanes. Suitable polyisocyanates include any aliphatic, cycloaliphatic or aromatic diisocyanate, a diisocyanate/monomeric polyol reaction product or an NCO-terminated polyurethane prepolymer. The catalyst system for the preparation of the prepolymer may be based on malonitrile, an alkali metal hydroxide or tertiary amine and a compound of a metal selected from Co, Sn, Pb, Bi, Fe and Zn. The compositions may comprise 10-200% wt. of fillers and 1-50% wt. of plasticizers based on the weight of the prepolymer, as well as surface-active agents; blowing agents, e.g. water, volatile hydrocarbons or halocarbons; heat stabilizers; flameproofing agents; U.V. absorbers; dyes and pigments. The compositions can be used for coating textiles particularly for coating carpet backings. In the examples, compositions are prepared by mixing (A) an NCO-terminated prepolymer prepared by reacting (1) either a polyether prepared by condensing propylene oxide and ethylene oxide on glycerol or (2) polyoxypropylene glycol and glycerol, with an 80/20 mixture of 2,4- and 2,6-toluene diisocyanate in the presence of aqueous KOH, malonitrile and dibutyltin dilaurate, with (B) 3 - methyl - 1 - phenyl - 1 - phosphocyclopent- 3-ene oxide dissolved in hexamethylphosphotriamide, a silicone/glycol copolymer surface active agent, and optionally either a mixture of calcined clay and rutile titanium oxide, or talc. The compositions are coated on to a tufted carpet and heated at 160‹ C. to form a cellular polyurethane layer on the backing of the carpet.

Title: Improvements in or relating to matte coatings on sheet materials
Inventor: BARBA ANDREW MICHAEL
IPC: C08J7/046
Filed: 1964-11-24
Abstract: A dense fine matte surface receptive to pencil and ink drawing and also suitable as a base for photographic emulsions is formed on a plastics or other sheet material by suspending finely divided inorganic pigment in an aqueous polyacrylic resin medium, applying the medium as a coating to the sheet material, drying, and heating the dried coating at a suitable temperature to accomplish thermosetting of the resin.  A sheet of plastics or other material is coated with a well adhering matte surfaced layer having good pencil receptive properties comprising a finely divided inorganic pigment, affording a good pencil tooth but smooth enough to receive a light-sensitive composition, and a thermosetting polyacrylic resin binder, the binder being hardened by heating to a temperature of 200 to 400 DEG F for 1 to 20 minutes. The hardening may be effected at between 270 and 340 DEG F for 2 to 10 minutes to produce a hard pencil receptive surface which is highly resistant to wear by extensive erasure and resistant to gouging by a hard sharp pencil. 0.1 to 5% by weight of zinc oxide or titanium dioxide, based on the pigment, may be included to improve opacity and whiteness.  The coating may be applied, e.g. by roller or blade, to the sheet material as a suspension of the finely divided pigment in an aqueous thermosetting acrylic resin binder medium, e.g. an aqueous solution or emulsion, the coating then being dried and hardened by heating. The pigment may be ground glass, oxides of aluminium or other metals, silicates, stearates, silica, diatomaceous earth, or starch.  The sheet material may be a film of polyethylene terephthalate or polycarbonate, or cotton or glass fabrics filled with polyester resins, lacquered or starched-filled cloth, paper, or cellulose acetate film.  The coating composition may be used to replace or touch-up damaged areas of the coating.  Light sensitive elements may be produced by further coating the coated sheet material with a composition containing combinations of diazonium compounds and coupling components, e.g. a composition containing cellulose acetate, 2-methoxyethanol, gamma butyro lactone, sulphosalicylic acid, 2, 2\sv, 4, 4\sv-tetra hydroxybiphenyl, p-diethylaminobenzene diazonium chlorozincate, thiourea, 2\sv, 3-dihydroxy-2-naphthanilide, and silica gel.  The further coating is dried, exposed through a positive line original and developed in an ammonia chamber.  The resulting print is blue black with a matte surface which accepts pencil.
