Abstract: A polymerizable material is formed by the reaction of: (A) acrylamide or methacrylamide; (B) from 1.5 to 2 moles, per mole of acrylamide or methacrylamide, of formaldehyde; and (C) an amount equivalent to the formaldehyde of a hydroxyl-group containing component comprising one or more hydroxyl or group-containing compounds containing from 1 to 4 primary or secondary hydroxyl groups per molecule, at least one of the hydroxyl groups-containing compounds being a monoacrylate or monomethacrylate of a diprimary, disecondary or primary-secondary diol, the said monoacrylate or monomethacrylate being used in an amount of from 0.1 to k mole, per mole of acrylamide or methacrylamide, when the average number of hydroxyl groups per molecule of the hydroxyl group-containing component is 1 and in an amount of from 0.

Abstract: A process for the preparation of a water-dispersible oleoresinous film-forming material comprises reacting a first hydroxyl group-containing oleoresinous film-forming material with an organic diisocyanate in an amount such that the ratio of isocyanate groups in the diisocyanate to hydroxyl groups in the oleoresinous film-forming material is about 2:1 to produce an adduct containing free isocyanate groups and subsequently reacting the adduct with a second hydroxyl group-containing oleoresinous film-forming material to form a diadduct containing the first oleoresinous film-forming material and the second oleoresinous film-forming material, one of said first and second oleoresinous film-forming materials being a relatively hydrophilic oleoresinous film-forming material and the other being a relatively hydrophobic oleoresinous film-forming material and the relatively hydrophilic oleoresinous film-forming material forming a minor proportion by weight, preferably from 5 to 20% by weight, of the total of relatively
