    摘要： (Meth)-acrylic acid esters of the formula ##STR1## in which R.sup.1 and R.sup.2 are each independently hydrogen, chlorine, fluorine or a C.sub.1 - to C.sub.4 -alkyl radical andR.sup.3 and R.sup.4 are identical or different and represent the group ##STR2## wherein Y is a divalent bridge member from the group ##STR3## and Z is a straight-chain or branched hydrocarbon chain which has 2 to 10 carbon atoms, can optionally contain oxygen bridges and is optionally substituted by 1 to 4 acrylate or methacrylate radicals,whereinR.sup.5 represents hydrogen or methyl andR.sup.6 represents hydrogen, C.sub.1 -C.sub.6 - alkyl or phenyl,which are useful as dental materials.

    摘要： Cationic crosslinkable polyamidoamine resins which are obtainable by reaction of(A) a water-soluble polyamidoamine prepared from(1) aliphatic or aromatic dicarboxylic acids or functional derivatives thereof, such as anhydrides, esters or half-esters, and .omega.-aminocarboxylic acids containing at least 3 C atoms or lactams thereof, and(2) a polyamine mixture of (.alpha.) polyamines which contain at least two amino groups which are capable of amide formation and at least one further secondary or tertiary amino group, and (.beta.) polyamines which contain only two amino groups which are capable of amide formation,(B) with an epihalogenohydrin, in a molar ratio of 0.7 to 3.5 mol of epihalogenohydrin per mol of basic nitrogen in component (A),(C) with an inorganic base and(D) with 0.2 to 9.0 mol of a halogen-free mineral or carboxylic acid, the acid being added in at least an amount to give a pH of at least 5,are used as agents for imparting wet strength to paper.
