Abstract
A photosensitive laminate structure including a carrier layer and a photosensitive layer is described. The photosensitive layer includes a polymeric photosensitive resin composition containing at least one cross-linkable unit represented by the formula: wherein X is an organic moity and Y is selected from the following group: wherein Z is selected from at least one of lithium, sodium, potassium, ammonium, monoalkylammonium, dialkylammonium, and tetraalkylammonium.
Claims13
A photosensitive laminate structure comprising:
- a carrier layer;
- and
- a photosensitive layer comprising:
- (a) a polymeric photosensitive resin composition containing at least one cross-linkable unit represented by the formula:
- wherein X is an organic moity and Y is selected from the following group:
- wherein Z is selected from at least one of lithium, sodium, potassium, ammonium, monoalkylammonium, dialkylammonium, and tetraalkylammonium;
- and
- (b) polyvinyl acetate;
- wherein the photosensitive layer comprises from 2 to 10 weight percent of the polymeric photosensitive resin and from 65 to 98 weight percent of the polyvinyl acetate based upon the total dry weight of the photosensitive layer.
A photosensitive laminate structure comprising:
- a carrier layer;
- a release layer;
- and
- a photosensitive layer, the photosensitive layer comprising:
- (a) at least 5 percent by weight of a polymeric photosensitive resin composition containing at least one cross-linkable unit represented by the formula:
- and
- (b) at least 75 percent by weight of a polyvinyl acetate.
A photoimaging process comprising:
- (a) exposing a photosensitive laminate to actinic radiation, the laminate comprising a carrier layer;
- a release layer;
- and a photosensitive layer, the photosensitive layer comprising:
- (i) at least 5 percent by weight of a polymeric photosensitive resin composition containing at least one cross-linkable unit represented by the formula:
- and
- (ii) at least 15 percent by weight of a polyvinyl acetate.
- (b) removing from the laminate those portions of the photosensitive layer that have not been exposed to actinic radiation;
- (c) applying the laminate to a substrate;
- and
- (d) selectively etching the substrate using an abrasive material.
