HC Deb 08 November 1949 vol 469 c108W
82. Mr. Platts-Mills

asked the President of the Board of Trade if he is aware that the use of the formula for mica mix which is required in the manufacture of ceiling papers, is restricted to firms in the Wallpaper Manufacturers' Association group; that this restriction prevents the marketing of ceiling papers at a price lower than those now obtaining; and if he will take steps to end this practice.

Mr. Bottomley

The hon. Member is presumably referring to a process for making wet ground mica, which is used in the manufacture of wallpapers and ceiling papers. I understand that Wallpaper Manufacturers, Limited, discovered this process by research, and it may be that other firms are not in possession of the formula; but I am not aware that this prevents the marketing of ceiling papers at lower prices. I am informed that Wallpaper Manufacturers, Limited, do in fact sell wet ground mica to their competitors.
