Abstract: The invention relates to the use of a polyolefin film as a medium to be written or printed on, according to which oxygen-containing groups are attached to one or both faces of the film surface by surface treatment. The polyolefin film is then highly surface-polarized by subsequently electrostatically charging it. Film thickness and surface weight and the electrostatic adhesive force produced are controlled by the degree of surface polarization in such a manner that the film, at least when the treated face is placed on a clean, dry and planar floatglass surface, will adhere to said surface indefinitely.

Abstract: A modified solid carrier is used to covalently immobilize biomolecules such as proteins. The carrier is based on well-known matrix materials modified to have covalently bound functional groups of formula I ##STR1## that are suitable for covalent immobilization, where A is a spacer group; X is O, S, or NH and n is 0 or 1. The modified solid carrier is prepared by reacting ammonia with glycidyl groups of a carrier to form .alpha.-hydroxy-.beta.-amino groups, reacting these groups with 2,4,6-trichloro-s-triazine to form an N-triazinyl group-containing carrier, reacting this carrier with ammonia and reacting the resultant carrier with 2,4,6-trichloro-s-triazine.
