摘要:
A composition for positive heat sensitive computer-to-plate (CTP) lithographic printing plates comprising a phenolic resin and an IR absorber characterized by the fact that the composition contains from 1 to 30% w/w of an organic oxygenated phosphorous compound chosen from the group of general formula (I): wherein R1, R2, and R3 are independently a C4–C8 alkyl group or an aryl group.
摘要:
Paper coating compositions contain specific polyethers which are obtained by reacting a diglycidyl ether with a water soluble polyol containing at least one polyoxyethylene chain acting as deflocculants, water retention agents and gloss enhancers.
摘要:
Non aqueous water dispersible compositions comprising: I) polyisocyanates, which are made hydrophilic by reaction with a 1,3- or 1,2-nonionic diol containing one alkoxy-terminated polyoxyethylene and/or polyoxypropylene chain, II) one or more ethoxylated alcohol phosphates having at least one phosphoric group in acid form, and optionally III) a water miscible organic solvent, the compositions being useful as crosslinker for polyurethane aqueous dispersions.
