Use of a composition in stereolithography

The use of a compound of formula (A), which comprises a group of sub-formula (I) where R1, R2, R3, R4, R5, R6, X1 and Y1 are various specified organic groups wherein at least one of said groups has sufficient electron whitdrawing properties to activate the multiple bonds to polymerisation, in a ster...

Zusammenfassung:	The use of a compound of formula (A), which comprises a group of sub-formula (I) where R1, R2, R3, R4, R5, R6, X1 and Y1 are various specified organic groups wherein at least one of said groups has sufficient electron whitdrawing properties to activate the multiple bonds to polymerisation, in a stereolithographic composition. Stereolithographic applications of these compounds are also described and claimed.
