ABSTRACT:
A coated product comprises a thermoplastic sheet support bearing on at least one surface an adhesion promoting cured layer comprising a composition of:
1) 30-80% by weight individually dispersed colloidal metal oxide particles, preferably silica, alumina and/or zirconia particles of average particle size 10-100 nanometers,
2) 20-70% by weight crosslinked polymer matrix derived from one or more polyethylenically unsaturated monomers, and
3) a photoinitiator.
Preferred embodiments of this invention include coated abrasive product in which the primed surface of the support layer is coated with a thermosetting binder containing abrasive particulates, and tape products in which the primed surface of the support layer is coated with a pressure-sensitive adhesive or magnetic media.
