Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
149 words
A method of optically connecting a light conductor to an electro-optical device by means of a curable lacquer, characterised in that the curable lacquer comprises from 40 to 95% by weight of at least one oligomer selected from the group of oligomeric acrylates, which lacquer furthermore comprises from 0.5 to 5% by weight of a heat- or light-acivatable initiator, the refractive index of the lacquer which is reached after curing being adjusted by the addition of from 2 to 30% by weight of a reactive diluent which has a refractive index-increasing influence and from 2 to 30% by weight of a reactive diluent which has a refractive index-reducing influence, said curable lacquer being contacted with the light conductor and the electro-optical device and after mutual positioning of the light conductor and the electro-optical device being cured by means of a rise in the temperature or by exposure to light.
Claim 2
Dependent Claim
24 words
A method as claimed in Claim 1, characterised in that the oligomer is selected from the group formed by polyester-urethane-acrylates and polyether-urethane acrylat s.
Claim 3
Independent Claim
30 words
A method as claimed in Claims 1 and 2, characterised in that the reactive diluent having a refractive index-increasing influence is selected from the group formed by N-vinyl-2-pyrrolidone, 2'-oxybenzophenone-2-ethoxy-ethyl- acrylate.
Claim 4
Independent Claim
25 words
A method as claimed in Claims 1 and 2, characterised in that the reactive diluent having a refractive index-reducing influence is 2-ethoxy-ethyl-acrylate or 2'- ethoxy-2-ethoxy-ethyl-acrylate.
Claim 5
Independent Claim
30 words
A method as claimed in any of Claims 1 to 4, characterised in that the initiator is azobsisobutyronitrile and that curing is carried out by a rise in the temperature.
Claim 6
Independent Claim
29 words
A method as claimed in any of Claims 1 to 4, characterised in that the initiator is α, α-dimethoxy-α-phenyl-acetophenone and curing is carried out by exposure to UV light.
Claim 7
Independent Claim
38 words
A method as claimed in any of Claims 1 to 6, characterised in that the oligomer is a polyester-urethane-acrylate shown in Fig. 1, in which m is on an average 2.6 and n is on an average 8.
Claim 8
Independent Claim
52 words
A method as claimed in any of Claims 1 to 6, characterised in that the ologomer is a polyether-urethane-acrylate shown in Fig. 2, in which n is on an anverage 75 and in which the reactive diluent having a refractive index-increasing influence is selected from the group formed by 2'-oxybenzophenone-2-ethoxyethyl-acrylate and 2-phenoxy-ethyl-.acrylate.
