Image transfer sheet and image forming method using the image transfer sheet

An image transfer sheet comprising

• a water-permeable supporter;
• a release layer overlying the water-permeable supporter and including a water-soluble release layer resin;
• an image supporting layer including image supporting layer resin;
• an image bearing layer overlying the image supporting release layer and including an image bearing layer resin;
• and
• an image on the image bearing layer,
• wherein a ratio L2/L1 is not less than 0.99, where
• L1 represents a length of one side of the image bearing layer when measured before the image transfer sheet is dipped into water, and
• L2 represents a length of the one side of the image bearing layer when measured after
• dipping the image transfer sheet into water,
• releasing the image bearing layer from the water-permeable supporter, and
• setting the image bearing layer on a wet acrylic plate;
• and
• wherein the image transfer sheet further comprises an adhesive layer between the release layer and the image
• wherein the adhesive layer is between the release layer and the image supporting layer;
• the image supporting layer is between the adhesive layer and the image bearing layer;
• and
• the image bearing layer, the image supporting layer and the adhesive layer constitute a combination layer.
