The invention relates to an image-recording element comprising a support and an image-receiving layer, wherein the image-receiving layer comprises anionic colloidal silica particles, hydrophilic polymeric binder, and fluorosurfactant, wherein the binder is present in an amount of between 2% and 15% weight of the image-receiving layer, the image-recording element has a 60-degree gloss of greater than 25, and a dry time of less than 1 minute.
The synthesis of double tail surfactants having crown ethers as polar heads was performed by reacting di‐F‐alkyl mercaptosuccinate on cyclic polyethylene glycol maleates. Surface tension and critical micelle concentration (CMC) were determined for these new surfactants. According to CMC values, the solubility in water is higher with perfluoroalkyl surfactants having a bigger loop size and shorter hydrophobic
