    摘要: The present invention relates to aqueous resorcinol-formaldehyde-latex dispersions comprising at least one carbodiimide based on compounds of the formula (I) R′—(—N═C═N—R—)m—R″  (I), where, m is an integer from 1 to 500, R=C1-C18-alkylene, C5-C18-cycloalkylene-, arylene and/or C7-C12-aralkylene, R′=R—NCO, R—NHCONHR1, R—NHCONR1R2, R—NHCOOR3 or R—NHCO—R5 and R″=—NCO, —NHCONHR1, —NHCONR1R2, —NHCO—R5 or —NHCOOR3, where R1 and R2 in R′ are mutually independently identical or different and are a C1-C6-alkyl moiety, C6-C10-cycloalkyl moiety or C7-C12-aralkyl moiety, and R3 is as defined for R1 or is a polyester moiety or a polyamide moiety or —(CH2)l—(O—(CH2)k—O)g—R4, —C8H4(OH) or —C8H3(OH)—((CH2)h—C6H4(OH))y and R5=epoxide, phenol, oxime, resorcinol, polyethylene glycols and/or lactam, preferably caprolactam, where l=from 1 to 3, k=from 1 to 3, g=from 0 to 12, h=from 1 to 2 and y=from 1 to 50, and R4=H or C1-C4-alkyl.
