Abstract: Aqueous emulsion of one or more water dilutable epoxide resins, containing10 to 70 wt % of one or more epoxide resins5 to 50 wt % of one or more organic solvents having a boiling point of 100.degree. to 160.degree. C.,10 to 70 wt % of water,and one or more chlorinated polyolefines in a weight ratio of epoxide resins:chlorinated polyolefine of 10:0.5 to 10:4.5, percentages by weight relating in each case to the total aqueous emulsion.The emulsions can be used for the preparation of coating agents, especially for coating plastic substrates.

Abstract: Two component-coating agents and emulsions which can be used for their preparation. The coating agents contain:A) 10 to 40 wt.-% of one or more polyols having a number average molecular weight (Mn) of 500 to 200000, an OH-number of 15 to 300 and a content of ionic groups and/or groups convertible into ionic groups of 5 to 400 meq/100 g solid resin, which are at least partly neutralized,B) 0.5 to 10 wt.-% of one of more chlorinated polyolefines having a chlorine content of 15 to 35 wt.-%,C) 5 to 40 wt.-% of one or more aromatic solvents having a boiling range from 100.degree. to 160.degree. C.,D) 25 to 75 wt.-% of water,E) 0 to 30 wt.-% of one or more further water dilutable binders which are free from groups reactive with NCO,the percentages by weight of components A) to E) adding up to 100 wt.-% andF) one or more polyisocyanates having on average at least two free isocyanate groups per molecule, in such an amount that the ratio of the number of reactive isocyanate groups to the OH-groups of the polyols is 0.

Abstract: An aqueous coating agent, containingone or more film-forming water-dilutable or water-soluble epoxy resins with an epoxide equivalent weight of 100 to 10000,one or more water-dilutable or water-soluble polyamines with at least two primary and/or secondary amino groups in the molecule and an equivalent weight of 50 to 500, andoptional pigments, fillers and/or other conventional lacquer adjuvants,the ratio of reactive H atoms in the polyamines to the epoxy groups in the epoxy resins being 0.7:1 to 1.5:1 and5 to 80 wt. % of one or more water-dilutable or water-soluble polyurethane resins with a number average molecular weight (Mn) of 500 to 500000 relative to the sum of the weights of the solids in the epoxy resin and polyamine.

Abstract: An aqueous coating agent on the basis of one or more polyols having ionic groups or groups convertible into ionic groups, which can contain pigments, fillers and/or optional conventional lacquer adjuvants and/or solvents, comprisingA) 10 to 40 wt.-% of one or more polyols having a number-average molecular weight (Mn) of 500 to 200000, an OH-number of 15 to 300 and a content of ionic groups and/or groups convertible into ionic groups of 5 to 400 meq/100 g solid resin, which are at least partly neutralized,B) 0.5 to 10 wt.-% of one or more chlorinated polyolefines having a chlorine content of 15 to 35 wt.-%,C) 5 to 40 wt.-% of one or more aromatic solvents having a boiling range from 100.degree. to 160.degree. C.,D) 25 to 75 wt.-% of water,E) 0 to 30 wt.-% of one or more further water dilutable binders which are free from groups reactive with NCO,the percentages by weight of components A) to E) adding up to 100 wt.
