Pre-treating film support of cellulose ace- - tate |
| 摘要 |
<p>Film support of cellulose acetate is pre-treated for the application of photographic emulsions, when gelatine binder in emulsion is replaced by synthetic high-polymers, by applying solution of copolymer of acrylic acid- or methacrylic acid esters with components containing vinyl groups from a solvent mixture of methanol, acetone and methylene chloride at 25-40 degrees C and drying at 60-120 degrees C. Sufficient adhesivity in wet and dry states is achieved.</p> |
