    • The present invention relates to a material intended for forming or printing images, comprising a support and at least one hydrophilic binder-based layer, and its manufacturing method, said method enabling the gelation process of the hydrophilic binder to be controlled. The material according to the invention is characterized in that in at least one of said hydrophilic binder-based layers, said hydrophilic binder is gelated by complexation with a complexing agent present on a heat-sensitive polymer or copolymer, that is hydrophobic at temperatures higher than its lower critical solution temperature LCST to protect the complexing agent, and water-soluble at temperatures less than its LCST to make the complexing agent accessible, the LCST of the heat-sensitive (co)polymer being higher than the setting temperature of said hydrophilic binder. The material according to the invention can be used as photographic material or as material taking aqueous ink compositions applied by the inkjet printing technique.

    • Water-based fluids that can viscosify under shear or can produce a gel or form a gel under shear are obtained by dissolving polymers in an aqueous phase. These polymers comprise three types of functional groups: non-ionic functional groups that are hydrosoluble at the temperature under consideration, ionic functional groups, and functional groups that are hydrophobic at the temperature under consideration. These three types of functional groups can be distributed or spread in a random distribution along the polymer chain. A slightly block distribution is acceptable. For applications to oil wells, functional groups are used which exhibit LCST (Lower Critical Solution Temperature) behavior (i.e., a low critical solution temperature) instead of hydrophobic functional groups. At temperatures below the LCST, the functional groups are hydrophobic.
    • 通过将聚合物溶解在水相中,可以获得在剪切下可以粘稠或可以在剪切下产生凝胶或形成凝胶的水基流体。 这些聚合物包括三种类型的官能团:在所考虑的温度下可溶于水的非离子官能团,离子官能团和在所考虑的温度下是疏水的官能团。 这三种类型的官能团可以沿着聚合物链分布或分布在随机分布中。 稍微块分布是可以接受的。 对于油井的应用,使用显示LCST(较低临界溶液温度)行为(即低临界溶解温度)而不是疏水官能团的官能团。 在低于LCST的温度下,官能团是疏水的。
