A method for preparing a substrate having an adherent, durable, flexible, and stain resistant layer. The layer is formed by applying a composition that includes (i) the reaction product of a polyester and a polyoxetane having at least one carboxylic acid end group and at least one pendant &#x2014;CH&#x2014;O&#x2014;(CH)&#x2014;Rf group and (ii) an amino resin curative. The substrate may be printed or embossed or both. The coated substrate has both stain resistant properties and dry erase properties.

Method of making an easily cleanable polymer laminate

A reactive fluorinated polymer having polyester and polyether segments is mixed with a reactive melamine resin to form a coating composition. The polyether segment can include monomeric units from an oxetane monomer having pendant fluorine groups that are linked to the oxetane via an ether group. The melamine resin can be a lower alkyl etherified melamine-formaldehyde. The composition can be disposed on a substrate and treated to form a laminate.

Fluorinated polymer and amine resin compositions and products formed therefrom

A polyester polymer includes at least one hydroxyl terminated polyoxetane block containing repeat units derived from polymerizing at least one oxetane monomer having a pendant &mdash;CH &mdash;O&mdash;(CH ) &mdash;Rf group wherein said Rf group is partially or fully fluorinated. A preferred process for forming said polymer is by reacting a hydroxyl terminated polyoxetane with a polycarboxylic acid under appropriate conditions to form an ester linkage and then adding and reacting that product with polyester forming reactants. The polyester polymer containing at least one polyoxetane block therein when reacted with an amino resin curative can be used as a coating on a substrate wherein the coating has dry erase properties. The coated substrate can be used as prepared or applied to yet other substrates.

Cured polyesters containing fluorinated side chains

A substrate having an adherent and stain resistant layer having durability and flexibility, said layer comprising the reaction product of a reactive polyester having free carboxylic acid and/or hydroxyl groups, a hydroxyl terminated polymer including repeat units from an oxetane having pendant &mdash;CH &mdash;O&mdash;(CH ) &mdash;Rf groups (said Rf groups generally being a fluorinated alkyl group) and an amino resin curative. The substrate may be printed or embossed or both. The coated substrate has both stain resistant properties and dry erase properties with dry erase markers. The coated substrate can be used as prepared or applied to other substrates.

Easily cleanable polymer laminates

A compounded and plasticized vinyl chloride polymer layer, optionally supported with a fabric, contains an outer adherent, stain resistant layer having durability and flexibility. The adherent, stain resistant layer is derived from a water-based polyester-amino resin composition. The stain resistant layer comprises the reaction product of said polyester, an acid catalyst, and an amino resin. The vinyl chloride layer may be printed or embossed or both printed and embossed, optionally printed again, before the outer layer is applied. A laminate formed from the polyvinyl chloride polymer layer and the stain resistant layer can also be embossed.
