The heat-sensitive water-soluble copolymer is obtained from a composition of water-soluble monomers comprising, for 100 molar parts (pp): from 10 to 69 pp of at least one compound (I) and/or (II); from 30 to 75 pp of at least one ethylenically unsaturated sulphonic acid; from 0 to 50 pp of at least one compound (III) and/or (IV); from 0 to 30 pp of at least one compound (V) and/or (VI); from 0 to 30 pp of at least one other monomer such as (VII) and/or (VIII) and/or (IX) and/or acrylonitrile and/or allyl alcohol and/or vinylpyridine and/or an unsaturated monomer which is a carboxylic acid or an anhydride of a carboxylic acid and/or a silane monomer and/or a phosphate-function monomer and/or a phosphonated monomer and/or a monomer having N-vinyl groups; and from 0.001 to 50 pp of at least one hydrophobic monomer.
