Claim 1

A method of producing three-dimensional objects from a composition comprising a compound of the formula H.sub.2 C═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 1 - or a C 2 -alkylene group; R 0 is a hydrogen atom or a methyl group; R 1 is a z-valent radical selected from aliphatic, cycloaliphatic, aromatic, aliphatic-aromatic and aliphatic-cycloaliphatic hydrocarbon radicals and polyoxyalkylene radicals; R 2 is a radical selected from the radicals of the formulae ##STR59## R 4 is a group selected from the groups of the formulae ##STR60## R 5 is a group selected from the groups of the formulae ##STR61## R 6 is a (2.z)-valent organic group which, together with the carbon atoms C.sup.α and C.sup.β 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 14 and R 15 are each a hydrogen atom or, when E! is a C 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 2 C═CH--O!-- 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.

Claim 2

A method of producing three-dimensional objects from a composition comprising a compound of the formula H.sub.2 C═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 1 - or a C 2 -alkylene group; R 0 is a hydrogen atom or a methyl group; R 1 is a z-valent radical selected from aliphatic, cycloaliphatic, aromatic, aliphatic-aromatic and aliphatic-cycloaliphatic hydrocarbon radicals and polyoxyalkylene radicals; R 2 is a radical selected from the radicals of the formulae ##STR59## R 4 is a group selected from the groups of the formulae ##STR60## R 5 is a group selected from the groups of the formulae ##STR61## R 6 is a (2.z)-valent organic group which, together with the carbon atoms C.sup.α and C.sup.β 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 14 and R 15 are each a hydrogen atom or, when E! is a C 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 2 C═CH--O!-- 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.
