Abstract of the Disclosure: Crosslinked acrylic or methacrylic acid copolymers with crosslinkable groups that are useful as thickeners for textile print pastes are obtainable by copolymerization of

Crosslinked copolymers with crosslinkable groups based on acrylic or

A process for the preparation of stable dispersions of finely divided polyisocyanates, and the preparation of heat-crosslinkable isocyanate systems. Stable dispersions of finely divided polyisocyanates in a liquid which may or may not contain surfactants, protective colloids and other assistants are obtained by a method in which polyisocyanates are treated with a stabilizer in the presence of absence of the liquid, and the dispersions prepared from these are finely dispersed and/or milled under the action of high shear forces, if necessary with the addition of further stabilizer. These dispersions are useful as crosslinking agents, particularly for the preparation of heat-cross-linkable isocyanate systems.

Preparation of stable dispersions of finely divided polyisocyanates and

Pigment printing pastes and dyeing liquors containing finely divided solid dispersions of polyisocyanates which have been deactivated on the surface and have a melting point about 25.degree. C. and a particle size of from 0.1 to 15 .mu.m as crosslinking agents in an amount of from 0.1 to 6% by weight. The textile materials printed or dyed with these pastes or liqu0rs, respectively, possess good fastness properties

Pigment printing pastes and dyeing liquors containing stable dispersions

Binders are used in printing inks and print pastes for transfer printing, consisting of copolymers of N-vinylcaprolactam, the use of these copolymers as binders in printing inks and printing pastes, and printing inks and print pastes containing these.

Binders for transfer printing

The subject invention relates to the use of foam inhibitors in printing pastes based on oil-in-water emulsions or aqueous emulsions. The foam inhibitors are mixtures of monoalkyphosphates and aliphatic esters or high boiling hydrocarbons.

Printing pastes with foam inhibitors

Oxyalkylated 1,3-bis-aryl-glycerol ethers of the formula ##STR1## where R and R.sup.1 are aromatic substituents, R.sup.2 is --CH.sub.3 or --C.sub.2 H.sub.5, R.sup.3 is --H or --CH.sub.3, n is from 0 to 10 and m is from 8 to 50. The compounds of the formula I are used as emulsifiers, preferably in the preparation of print pastes.

1,3-Bis-aryl-glycerol-ethers

1,3-Bis-aryl-2-oxyalkylated-glycerol ethers

A method of printing fibrous materials using a print paste incorporating as emulsifier a di-(.alpha.-phenylethyl)-phenol which has been first reacted with from 2 to 12 moles of propylene oxide and/or butylene oxide and then with from 14 to 30 moles of ethylene oxide.

Process for printing fibrous material

Cyclic acetals or ketals of carbonyl compounds having at least one aliphatic or aromatic radical, and polyhydric alcohols which have at least one more hydroxyl group than those required for acetalization, and which are furthermore oxyalkylated at the free hydroxyl group or groups.
