Comparative Examples 1-3

[0152] Comparative compositions without (d) absorbers are prepared as follows. In a glass bottle, RuI (0.0046 g) and CPTX (0.0030 g) are dissolved in PENB (10 g) without solvent to form a clear composition.

##STR00022##

5-phenethylbicyclo[2.2.1] hept-2-ene (PENB)

##STR00023##

1,3-bis(2,4,6-trimethylphenylimidazolidin-2-ylidene) (tricyclohexylphospine)-(2-oxobenzylidene) ruthenium (VI) iodide (RuI)

##STR00024##

1-chloro-4-propoxy-9H-thioxanthen-9-one (CPTX) Each composition is spin coated under nitrogen atmosphere on pre-cleaned Quartz substrates, to be wet films. The wet films are illuminated with UV light of 395 nm under nitrogen atmosphere to cure the film, the dose applied was in general between 0.5 and 5 J/cm.sup.2. The dose used for the comparative examples is given in Table 1. The spin coating parameters are optimized to obtain 8 m film thickness. The film thickness is determined by profilometry after curing the film and scratching with a scalpel to reference to the substrate surface.

[0153] After sample preparation, transmission spectra are registered in the wavelength range 250-800 nm.

Working Examples 1-17

[0154] Working example compositions are prepared as follow. Except for adding (d) absorber, working example compositions are prepared in the same manner to the comparative composition 1. The amounts of (d) absorber comparting to the total of the composition are described in Table 1.

[0155] It is confirmed that working example compositions shows good transmission in visible range (450-800 nm) and UV light transmission reduction (250-450 nm).
