PROCESS OF TREATMENT OF SURFACE WITH COLOFONIA AND POLYETHYLENE-GLYCOL ESTERS |
| abstract |
Paper and paper-like products are treated with a composition made by fortifying rosin with an alpha , beta -unsaturated organic acid or anhydride and subjecting the resultant product to esterification with a polyoxyalkylene glycol, the effect of the treatment being to increase the coefficient of friction of the paper surface. Improved sizing is obtained by treating the paper in addition with a retention aid, such as a polyaluminium chloride. |
