This specification discloses non-aqueous solvent, pigmented ink formulations that are suitable for the electronic and aerospace industries and form printed marks that are resistant to smearing and dissolution by organic solvents commonly used in overcoatings in this industry and others. These ink formulations are based on use of an acidic resin with an inherent acid value of at least about 25 mg KOH/g, preferably at least partially neutralized by a quaternary ammonium hydroxide and/or alcohol amine acid neutralizing or modifying agent.

A composition contains quantum dots (A) and a resin (B), wherein the resin (B) contains a polymer (B1) having a sulfide group, a carboxyl group, and an unsaturated double bond.

The present disclosure provides an aluminum phosphite-based complex with dual-peak thermal gravity decomposition characteristics and a preparation method and use thereof. A structural formula of the complex is as follows: ((HPO.sub.3).sub.3Al.sub.2).((H.sub.2PO.sub.3).sub.3Al).sub.x, wherein x is 0.01-0.5 and represents a molar ratio of (H.sub.2PO.sub.3).sub.3Al to (HPO.sub.3).sub.3Al.sub.2. The dual-peak thermal gravity decomposition characteristics are as follows: a first gravity peak temperature is 460-490° C., and a second gravity peak temperature is 550-580° C. The preparation method includes: uniformly mixing aluminum phosphite and aluminum hydrogen phosphite according to the ratio in the structural formula, and then performing stepwise heating at a rate of 5° C./min to raise the temperature of a mixture from the normal temperature to no more than 350° C. within 1-10 hours, so as to obtain the aluminum phosphite-based complex with the dual-peak thermal gravity decomposition characteristics. The complex may serve as or is configured to prepare a flame retardant or a flame-retardant synergist.
