    Abstract: The invention relates to the use of an aqueous binding agent devoid of formaldehyde for substrates, having a large molecular weight distribution. Said binding agent contains (A) 0 - 100 wt. % of an ethylenically unsaturate d acid anhydride or an ethylenically unsaturated dicarboxylic acid, whereby th e carboxylic acid groups thereof can form an anhydride group, or mixtures thereof, (B) 100 - 0 wt.- % of an ethylenically unsaturated compound, (C) at least one polyfunctional cross-linking agent or mixtures thereof. The polyme rs made from A) and B), obtained by radical polymerisation, classified in a coodination system according to the average molecular weight thereof Mw and the polydispersity value thereof, are arranged on a surface above a straight line which is defined by the straight equation y = 1.25x + 20000 and is displaced in direction y in a parallel manner by at least + 3000. The x axis characterises the average weight of the molecule and the y axis characterise s the polydispersity multiplied by 10000.
