    摘要： A hydroxy-functional polymeric dispersant which is substantially free of acid groups, amine groups, and ethylenic unsaturation, the dispersant being especially adapted for dispersing pigments therein and being compatible with a variety of film-forming polymers, said dispersant being the free radical addition polymerization reaction product of a mixture of monomers consisting essentially of:(a) 15-30% by weight styrene; and(b) 15-30% by weight of at least one alkyl methacrylate monomer having 1 to 16 carbon atoms in the alkyl group; and(c) 20-60% by weight of at least one alkyl acrylate monomer having 1 to 16 carbon atoms in the alkyl group; and(d) 7-25% by weight of at least one hydroxy-functional ethylenically unsaturated monomer copolymerizable with monomers (a) (b) and (c);wherein said polymeric dispersant has a weight average molecular weight of 18,000 to 24,000, a number average molecular weight of 4,500 to 7,400, and a polydispersity of 2.9 to 4.2.

    摘要： A stack of aligned sheets, each of which sheets includes a backing, a coating of pressure sensitive adhesive on a lower surface of the backing by which the sheet is adhered to the sheet beneath it in the stack, which coating extends along and within at least 12.5 mm of all of the edges of the backing, release means providing a first adhesion zone between adjacent sheets in the stack and adjacent one of the edges of the sheet for providing a sufficiently low release force between the adhesive coating and the upper surface of the adjacent sheet in the stack to afford, when the sheet is the uppermost sheet in the stack, each initiation of peeling of the sheet from the adjacent sheet in the stack, and attachment means providing a second adhesion zone between adjacent sheets in the stack for providing a sufficiently high release force that is higher than said low release force in the first adhesion zone to firmly adhere adjacent sheets in the stack together and thereby hold the stack of sheets together during handling, while affording continued peeling away of the uppermost sheet in the stack after initiating of such peeling along the first adhesion zone.

    摘要： Water-dispersible (including water-soluble) salts of water-soluble amines with the anionic products formed by reacting at 200.degree. C. to 250.degree. C. a substantially neutral ester of a C.sub.14-20 saturated fatty alcohol with an ethylene-dicarboxylic acid which has been reacted with about 1/7 to 1/35 of its weight of a ethylenedicarboxylic compound of acidic character (for example maleic acid) are efficient agents for inhibiting the deposition of pigment in pigmented aqueous lacquers. Organic solutions of the salts are storage-stable. The salts can be incorporated into the lacquer during formulation of the lacquer or at a later point.
