Abstract
Provided are compositions derived from a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer. The compositions can be used to prepare color filter films that exhibit lower lip heights, suitable in color filter elements, for example, in liquid crystal display devices.
Claims33
A thermal transfer donor element comprising:
- a. a support;
- and
- b. a thermal transfer layer disposed upon the support, wherein the thermal transfer layer is derived from a composition comprising a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer present in an amount ranging from 1 to 15 wt % of the composition;
- and
- c. a laser dye.
2 more elements
A process comprising:
- a. a coating a support with a composition comprising:
- (i) a polycarboxylic acid;
- (ii) a plasticizer comprising 1 to 15 wt % of the composition;
- (iii) a copper phthalocyanine complex;
- and
- (iv) a laser dye;
- and
- b. heating the coated support.
5 more elements
An imageable assemblage comprising:
- a. a donor element comprising a transparent donor support with a first and second surface, and a thermal transfer layer disposed on the second surface of the support, wherein the thermal transfer layer is derived by heating to 40° C. to 60° C. a composition comprising a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer comprising 1 to 15 wt % of the composition;
- and
- b. a receiver in contact with the thermal transfer layer of the donor element.
A process comprising:
- a. directing laser radiation to a first surface of a transparent donor support of a donor element of an imageable assemblage, wherein the imageable assemblage comprises a donor element comprising a transparent donor support with a first and second surface, and a thermal transfer layer disposed on the second surface of the support;
- and a receiver in contact with the thermal transfer layer of the donor element;
- b. heating a portion of the thermal transfer layer to cause it to transfer to the receiver;
- and
- c. separating the receiver from the donor element;
- and wherein the thermal transfer layer is derived from a composition comprising a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer present in an amount ranging from 1 to 15 wt %.
3 more elements
A thermal transfer donor element comprising:
- (a) a support;
- and
- (b) a thermal transfer layer disposed upon the support, wherein the thermal transfer layer is derived from a composition comprising a polycarboxylic acid, a copper phthalocyanine complex, and a plasticizer selected from the group consisting of tris(hydroxyalkyl) phosphines, phosphoramides, trifluoroacetophenones, and dialkylsulfoxides;
- and
- (c) a laser dye.
