increase the crosslink density but also reduce stoving temperatures to 130- 140°C. EP-714951508108458 Laminated film with white pigment for magnetic card Diafoil Hoechst Co Ltd A coext.rusion lamination of biaxially oriented polyester film containing a polyester layer containing a white-coloured pigment having a b value (JIS Z-8277 measured with a colour anlayzer TC 1800 MKII RTM: Tokyo Densyoku KK) of < 5, and at least one layer containing 1% recycled polymer by weight, produces a low-cost high-quality magnetic card, with high adhesion to magnetic and printing layers and good durability. JO8 109299 PVC with improved transparency and resistance to plate-out Chisso Corporation Priority date: 13 October 1994 A vinyl chloride compound containing alkali metal or alkaline earth metal 2-propylheptanoates, epoxy soyabean oil and phosphites is useful for flexible extruded products and injection moulded components. It offers improved transparency, and resistance to plate-out, heat and discolouration. JU08 108509 Structural material made of palm fibres Nagoya E’uke KK Priority date: 7 October 1994 A structural material which is light in weight and has superior stiffness and mouldability at low or room temperature can be produced with palm fibres or mixed fibres including palm, combined with a polyhydric phenolaldehyde type condensation compound and cured.
