Patent Images
1. A laminated film comprising:
- a base film; and
a layer which contains (a) an inorganic layered compound, and (b) a resin, said layer being formed by gravure coating a coating fluid comprising the inorganic layered compound and the resin under the conditions satisfying the following equation (1);
space="preserve" listing-type="equation">7<
log (2((G/B)×
100).sup.2 ×
(B+G).sup.2 ×
(GM))<
13(1)wherein G is a rotational speed of a gravure roll (m/min.), B is a rotational speed of a backing roll (m/min.) and GM is a mesh number of a gravure roll, wherein the inorganic layered compound is an inorganic compound having a layered structure in which unit crystalline layers are laminated.

Abstract
A laminated film comprising a base film and a layer which contains an inorganic layered compound and a resin and is formed by gravure coating a coating fluid comprising the inorganic layered compound and the resin under the conditions satisfying the following equation:
7<log 2((G/B)×100).sup.2 ×(B+G).sup.2 ×(GM)!<13
wherein G is a rotational speed of a gravure roll (m/min.), B is a rotational speed of a backing roll (m/min.) and GM is a mesh number of a gravure roll, which film has good transparency and gas barrier properties.
