Zirconium bromonorbornanelactone carboxylate triacrylate (PRM30) is a zirconium-containing multifunctional acrylate useful for producing cured, transparent films with high refractive indices. It can be used alone or blended (formulated) with other metalcontaining acrylates:
PRM30 and PRM30/metal acrylate blends can be used in combination with other cross-linkable, film-forming macromers such as diurethane dimethacrylate and dipentaerythritol penta-/hexa-acrylate (Cat. No. 407283). Recommended amount of PRM30 to be used in these formulations is 50–100 weight % (excluding solvent).
Film-forming formulations employing PRM30 can be prepared in a number of organic solvents, including:
Recommended total solid content in these formulations is between 10–20 weight %. A combination of 2-butanone and 1-propanol solvents is preferred for improved shelf life stability of the formulations.
Films prepared from the above formulations can be cross-linked using a UV-radiation initiator, e.g., 1-hydroxycyclohexyl phenyl ketone (Cat. No. 405612) or using heat-sensitive initiators, such as benzoyl peroxide (Cat. No. 179981) and 2,2'-azobis (2-methylpropionitrile) (Cat. No. 441090).

Procedure Preparation of a high refractive index film on PET substrate, e.g., Toray Lumirror®
Films containing PRM30 show higher refractive indices compared to films with similar composition containing dipentaerythritol penta-/hexa-acrylate or zirconium acrylate (Table 1).
