A latex composition and an element containing a polymer layer derived from the composition. |
| 摘要 |
<p>A latex composition comprising a continuous aqeuous phase having dispersed therein core-shell polymer particles characterized in that the core polymer represents 80 to 95 weight percent of the entire particle and has a glass transition temperature greater than 70 DEG C, and the shell polymer represents 5 to 20 weight percent of the entire particle and has a glass transition temperature from 25 DEG C to 60 DEG C. The latex may be used to form an overcoat for a photographic element which is resistant to ferrotyping.</p> |
