Vinyl ether compounds having additional functional groups other than vinyl ether groups and the use thereof in the formulation of curable compositions

A method of producing three-dimensional objects from a composition comprising a compound of the formula

• ›H.sub.2 C.dbd.CH--O!--.sub.z A,
• the symbols used in that formula and in the formulae below having the following definitions:
• A is a z-valent radical selected from the radicals of the following formulae (1), (2), (3)
• and (4) ##STR57## ›D! is a group of the formula ##STR58## ›E! is a C.sub.1 - or a C.sub.2 -alkylene group;
• R.sup.0 is a hydrogen atom or a methyl group;
• R.sup.1 is a z-valent radical selected from aliphatic, cycloaliphatic, aromatic, aliphatic-aromatic and aliphatic-cycloaliphatic hydrocarbon radicals and polyoxyalkylene radicals;
• R.sup.2 is a radical selected from the radicals of the formulae ##STR59## R.sup.4 is a group selected from the groups of the formulae ##STR60## R.sup.5 is a group selected from the groups of the formulae ##STR61## R.sup.6 is a (2.z)-valent organic group which, together with the carbon atoms C.sup..alpha. and C.sup..beta. of each of the z groups of the formula ##STR62## in a radical of formula (2), forms a cycloaliphatic ring having at least 5 carbon atoms;
• R.sup.14 and
• R.sup.15 are each a hydrogen atom or, when ›E! is a C.sub.2 alkylene group, are each a hydrogen atom or together form a methylene group;
• i is an integer from 0 to 20;
• m is an integer from 1 to 20;
• s is an integer from 2 to 10;
• t is an integer from 0 to 10;
• u in the individual units of the formula ##STR63## in formula (5) are independently of one another an integer from 1 to 20;
• v is an integer from 0 to 4;
• x and
• y are independently of one another an integer from 2 to 20, and
• z is the number 1 or 2,
• a photoinitiator and, optionally, at least one other polymerizable compound different from the vinylether compound of formula ›H.sub.2 C.dbd.CH--O!--.sub.z A, which method comprises a step in which the surface of a layer of the composition is irradiated over its entire surface or in a predetermined pattern with an UV/VIS light source, so that in the irradiated regions a layer of the desired thickness is solidified, and then a fresh layer of the composition is formed on the solidified layer, and that fresh layer is likewise irradiated over its entire surface or in a predetermined pattern, and as a result of the repeated coating and irradiation there are obtained three-dimensional objects consisting of a number of solidified layers adhering one to another.
