Patent ID: 6929821

Claim:
A process for forming a pattern of fluorescent substance into the cell of a fluorescent substance display substrate comprising providing inside the cell two separate layers which are (i) a resin composition (A) layer and (ii) a photosensitive resin composition (B) layer, exposing the layers to light, developing the exposed layers, and baking the developed layers; wherein the resin composition (A) layer is not photosensitive and consists essentially of an acrylic polymer (a) having a weight average molecular weight of 10000 to 300000 and an acid number of 80 to 250 mgKOH/g, a fluorescent substance (b), a compound containing at least one ethylenically unsaturated group (c) having a viscosity of 5-15000 mPa.sec at 20° C., and 0.1 to 15 parts by weight of a polymerization inhibitor (d) based on 100 parts by weight of the acrylic polymer (a), the resin composition (A) layer is disposed between the inside of the cell and the photosensitive resin composition (B) layer, and the photosensitive resin composition (B) comprises a photoinitiator.
