Embodiment 1
[0133] This example illustrates the use of cationic photoinitiators as energy-active compounds and the change in their luminescence under UV energy radiation. 100.0 g of styrene-acrylic copolymer JONCRYL TM 611 (Johnson polymer) was dissolved in 400.0 g of acetone to make a resin solution, designated Solution 1. The dye solution was prepared by dissolving about 1% of the luminescent europium organic complex dye LUMILUX CD-331 in solution 1. Add a different energy active compound to each solution. These solutions are summarized in Table 19.
[0134] Solution number
[0135] *5% ethanol was used instead of 5% solution 1 to stabilize TPPBr.

[0138] c Aldrich, Inc.
[0139] The ink was stretched on an aluminum plate using a #8 steel stretch bar to produce solid tensile specimens for each solution in Table 19. Cut the aluminum sheet into small strips. The strips were exposed to a hand-held UV l...
Embodiment 2
[0145] This example illustrates the use of halogenated photoacid generators as energy active compounds and changes in luminescence under UV energy radiation. As shown in Example 1, several more representative solutions were prepared. The dye solution was prepared by dissolving about 1% of the luminescent europium organic complex dye LUMILUX CD-331 (Honeywell Corp.) in Solution 1. A different energy active compound was added to each solution. These solutions are summarized in Table 21.

[0147] a Aldrich, Inc
[0148] The solutions in Table 21 were run as described in Example 1 under the same exposure and analytical conditions. The results are given in Table 22.
[0149] solution
[0150] The results in Table 22 illustrate that certain types of halogenated compounds, such as DBCH and TBE, are advantageous in the present invention.
Embodiment 3
[0152] This example illustrates the use of certain nonionic photoacid generators as energy active compounds. As shown in Example 1, several more representative solutions were prepared. The dye solution was prepared by dissolving about 1% of the luminescent europium organic complex dye Lumilux CD-331 (Honeywell Corp.) in Solution 1. A different energy active compound was added to each dye solution. These solutions are summarized in Table 23.
[0153] Solution number

[0155] b CGI-263 from Ciba Specialty Chemicals
[0156] The solutions in Table 23 were run as described in Example 1 under the same exposure and analytical conditions. The results are given in Table 24.
[0157] solution
[0158] As can be seen in Table 24, various other known photosensitive compounds also work well in the present invention, especially when combined with short wavelength radiant energy.
