UV RADIATION DOSE INDICATORS Russian patent published in 2012 - IPC G03C1/685 G03C1/73 G01T1/08 G03F7/04 

FIELD: physics.

SUBSTANCE: invention relates to a composition which changes colour depending on the absorbed radiation dose, and use thereof as a UV radiation dose indicator. Described is a composition which changes colour depending on the absorbed radiation dose. The composition contains (a) an acid-sensitive dye and (b) a photolatent acid - sulphonyl oxime of formula . The invention also describes a method of determining radiation dose and a UV radiation dose indicator using a substrate coated with said composition.

EFFECT: invention provides efficient determination of energy dose onto a substrate having said coating, and determination of critical parts of the coating, for which radiation is insufficiently intense to ensure sufficient curing.
