The purpose of the article is to investigate the mechanisms of sponsorship in the marketing of art in the art market in order to expand the opportunities for the population to visit institutions and events in the field of culture and art, where works of fine art are displayed. It is determined that in the field of fine arts sponsorship has certain features, because the sponsor provides assistance, strengthening its image, receiving advertising and PR. In addition, the desire of sponsors to make their own demands on the content and conditions of placement and demonstration of art collections is becoming a trend. The research methodology is to apply empirical and comparative methods. This approach allows us to reveal and analyze the possibility of applying the specifics of sponsorship as a technology to ensure public access to works of art in art marketing. The scientific novelty of the article is to identify marketing mechanisms that make it possible to make sponsorship in the field of fine arts comprehensively justified, regulated, fair and legal. Conclusions. We analyzed the conditions and opportunities for sponsorship, as well as opportunities for broad sections of the population to access works of art in Ukraine and other countries. It should be noted that there is a tendency in the world to "settle" famous works of art in private collections, to which only a limited number of spectators have access. Collections of state museums remain freely available to the general public, most of whom do not now have the opportunity to purchase very expensive works of art at auctions and galleries. Sponsorship in the field of art has its own specifics, because often the sponsor often not only demonstrates his help to museums, strengthening his image, reputation, but also tries to "dictate" museums and galleries their requirements for organizing museum exhibitions, the sequence of acquisition of new works in museum collections. Marketing technologies allow to regulate the work between sponsors and cultural institutions, to make this cooperation reasonable and fair. According to the experience of the countries of the world, the most effective type of "cultural economy" depending on the mechanisms of financing culture and art can be called "Anglo-American" type, where financing is carried out by attracting private capital, including tax benefits.
