Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
131 words
A laminated optical component which comprises a supporting member manufactured from a transparent inorganic material and has on at least one side a layer of a radiation-cured lacquer the free surface of which has a defined shape, characterized in that the lacquer comprises at least 50% by weight of a compound which satisfies the formula wherein R 1 is a hydrogen atom or a methyl group, R is a group which satisfies the formula -O-R 2 - (2) or -o-R 3 -0-R 4 - (3) wherein R 2 is an alkylene group having 2-8 carbon atoms which may be substituted with one or more hydroxyl groups, R 3 and R 4 are equal or different and each represent an alkylene group having 1-4 carbon atoms, and m = 0 or 1.
Claim 2
Dependent Claim
131 words
A laminated optical component which comprises a supporting member manufactured from a transparent inorganic material and has on at least one side a layer of a radiation-cured lacquer the free surface of which has a defined shape, characterized in that the lacquer comprises at least 50% by weight of a compound which satisfies the formula wherein R 1 is a hydrogen atom or a methyl group, R is a group which satisfies the formula -O-R 2 - (2) or -o-R 3 -0-R 4 - (3) wherein R 2 is an alkylene group having 2-8 carbon atoms which may be substituted with one or more hydroxyl groups, R 3 and R 4 are equal or different and each represent an alkylene group having 1-4 carbon atoms, and m = 0 or 1.
