04189399 is referenced by 44 patents and cites 8 patents.

A composition is described comprising at least two co-crystallized acetylenic compounds, of different chemical structures, each containing at least one --C.tbd.C--C.tbd.C-- group and substituents selected from the group consisting of sulfonate, urethane and alcohol radicals, at least one of the compounds capable of undergoing a contrasting color change upon exposure to actinic radiation or thermal annealing, wherein the composition exhibits a substantially different thermogram than the sum of thermograms of the individual components as obtained by differential scanning calorimetry.

A device is also described useful for measuring the time-temperature or radiation-dosage history of an article comprising a substrate having deposited thereon the described composition.

A process is also described for producing the composition of this invention.
