CA 2298683

According to the present invention, a bulky sheet can be obtained without reducing the effect of a sizing agent. Thus, an ester compound having the melting point of not more than 100°C selected from (A) an ester compound of a polyhydric alcohol and a fatty acid and (B) an ester compound of a polyhydric alcohol and a fatty acid further including from more than 0 mole to less than 12 moles on the average of C2-4 oxyalkylene groups per 1 mole of the said ester compound is used as a paper bulking promoter.

L'invention concerne des agents gonflants pour le papier, qui permettent d'obtenir des feuilles bouffantes sans perturber l'activité des solutions de collage. Ces agents gonflants contiennent un composé ester choisi entre a) les esters d'acides gras d'alcools polyhydriques; et b) les esters d'acides gras d'alcools polyhydriques possédant 0 à 12 moles (uniquement) de groupe oxyalkylène C2-C4 par mole dudit composé ester. Ce dernier a un point de fusion égal ou inférieur à 100 DEG C.
