Abstract
A reactive ink composition comprising a UV-C radiation sensitive polymer, an acid scavenger, a photoinitiator, and a pH-sensitive dye. A method to print a composition onto a UV-C radiation dosimeter using a “layer-by-layer” deposition technique, as well as a dosimeter comprising the reactive ink composition, useful in monitoring the efficiency of a UV-C radiation sterilization or disinfection process.

A composition comprising:
- a UV-C radiation sensitive polymer,
- an acid scavenger,
- a photoinitiator, and
- a pH-sensitive dye,
- wherein the photoinitiator is 9% to 15% in weight of the composition.
A composition comprising 10% to 30% in weight of a UV-C radiation sensitive polymer, 0.25% to 0.75% in weight of an acid scavenger, 9% to 15% in weight of a photoinitiator, 0.5% to 1.5% in weight of a pH-sensitive dye, 0.1% to 0.3% in weight of a radiation screening agent, 0.25% to 0.75% in weight of background dye and 43% to 73% in weight of a solvent.
